Test review: Gas behavior and Energy, force, motion and work Group Work : Instructions Research, discuss and prepare (15 mins) Present and share (5 mins) Present your group’s topic Work in your group on in order of group number. your given topic. Each group member Use texts & visuals to should share their findings support your answers. with the class. Evaluate (5 mins) Peer review: assess your peers answers How would you do things differently? What did you like about their presentation. 2 Group 1 : Boyle’s Law Identify the relationship between pressure and volume. Describe how the particles of gas behave as volume decreases and pressure increases. Understand the concept of an inversely proportional relationship. If the temperature of a gas is kept constant, what will happen to its volume if the pressure decreases. Analyze the graph depicted below. At what volume did the gas have a pressure of 6 (atm). Analyze and Interpret data: Looking at the graph below what does the x-axis resemble. 3 Question 1:Identify the relationship between pressure and volume. The relationship between both of them are inversely proportional because as pressure increases volume decreases as seen above. (The original slide was deleted by someone? feel free to tell me who) Question 2: Describe how the particles of gas behave as volume decreases and pressure increases Gas moves rapidly and has many collision when volume decreases but when volume increases the gas particles move at a much low collision speed as seen above. Question 3:Understand the concept of an inversely proportional relationship. Answer: If one variable decreases, the other increases in the same proportion If the temperature of a gas is kept constant, what will happen to its volume if the pressure decreases. Nothing. Because in boyle’s law temperature has nothing to do with the Volume or Pressure. And as seen above there is no temperature measurement there. Question: Analyze the graph depicted below. At what volume did the gas have a pressure of 6 (atm). So as stated in boyle's law Volume (V) and Pressure (atm) are inversely proportional. A simpler meaning is that as Volume increases pressure decreases and vice versa. So in the graph if the pressure increases to 6 atm then the Volume will be 1L. Analyze and Interpret data: Looking at the graph below what does the x-axis resemble. The X-axis here resembles the Inverse Pressure or the line at the bottom. How? Because Ms.Lesly told us this. Group 2: Charles Law Identify the relationship between temperature and volume. What happens to the volume of gas when the temperature increases and pressure is kept at a constant according to Charles’s Law. Describe how the image below depicts Charles Law Explain how the particles in a gas behave as temperature decreases and volume decreases. Understand the concept of a directly proportional relationship. How can Charles's Law be demonstrated by observing the behavior of a hot air balloon? 10 1. Identify the relationship between temperature and volume. The relationship between temperature and volume is directly proportional to its absolute temperature at constant pressure//….. CHARLES’S LAW 2. What happens to the volume of gas when the temperature increases and pressure is kept at a constant according to Charles’s Law. According to Charles’s Law because of the temperature increasing the volume also increases making it directly proportional 3. Describe how the image below depicts Charles Law By Noor Bucheery The image depicts Charles Law because according to to charles law as volume increases temperature increases. The image shows that in volume 2 they added more heat (tempature) so the volume increased. 4. Explain how the particles in a gas behave as temperature decreases and volume decreases. The gas particles move more slowly. by. Maryam Ghuloom Relationships 5. Understand the concept of a directly proportional relationship. If two things are directly proportional, they increase or decrease together. How can Charles's Law be demonstrated by observing the behavior of a hot air balloon? When the pressure in the gas is held constant it increases the temperature which means increasing the volume By noor bucheery Group 3: Lussac’s Law Describe the relationship between temperature and pressure. If a gas is heated at a constant volume, what happens to the pressure of the gas? Explain how particles of a gas behave as temperature increases and pressure increases. Connect to the real-world, how does Lussac’s law apply to a pressure cooker? Understand the concept of a directly proportional relationship. What happens to the pressure of a gas when temperature decreases and volume remains the same? 17 Describe the relationship between temperature and pressure. In Lussac’s Law, As the temperature increases the pressure will also increase. They are directly proportional. Jood Kadhem If a gas is heated at a constant volume, what happens to the pressure of the gas? When you add heat to a constant volume of gas, the temperature goes up. So does the pressure. Now imagine you let that volume expand a little and let the pressure push outwards until you get back to the starting pressure. The gas will cool down a little as it does that work. Saja Alkhaja Explain how particles of a gas behave as temperature increases and pressure increases Because the mass of these particles is constant, the particles have to move faster as the gas becomes warmer. If they move faster, the particles will exert a greater force on the container each time they hit the walls, which leads to an increase in the pressure of the gas. Saja Alkhaja Yusuf Alsanad Connect to the real-world, how does Lussac’s law apply to a pressure cooker? inside a pressure cooker the food that you want to cook sits in water. As the temperature of the liquid water is increased, water vapour (water in its gas state) is produced. This vapour cannot escape the pressure cooker – meaning the volume is not changing. Understand the concept of a directly proportional relationship. The decrease and increase together. Such as pressure,temperature,and volume. Jood Kadhem What happens to the pressure of a gas when temperature decreases and volume remains the same? In Lussac’s Law, pressure and temperature are directly proportional, so as the temperature decreases pressure will decrease. That happens at a constant volume. Zainab Ali Group 4: Energy What is energy? Explain how energy is transferred in riding a bicycle. Give an example in which energy produces a force that causes motion. What is the S.I unit used for energy? 24 Hassan Almarzooq, Mohammed Alameer, Alreem Aldoseri What is Energy? Energy is the ability to do work or cause change. Energy can exist in many forms, kinetic, Potential, mechanical, chemical, nuclear and thermal energy Explain how energy is transferred in riding a bicycle. Chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. 25 Give an example in which energy produces a force that causes motion. Burning fuel moves a car, creating motion energy. c 26 What is the S.I unit used for energy? The joule 27 Mahmood, Bader Seyadi, Ali Alsendi Jood Almahmood Group 5 : Motion What is motion? Analyze the image shown above. Identify an object that is in motion. Describe how you know the object is moving. Describe what is a reference point. Suppose the man is in motion what might he use as a reference point as he moves from one house to another? Bader Seyadi What is motion Anser;We can define motion as the change of position of an object with time. Jood and mahmood ANALYZE In the picture shown We can see a man standing near a store and a plane soaring atop another In the other picture shown next to it, we see that the man has not changes while the plane has moved to another store This shows that MOTION has taken place Since let's assume that the man was the plane’s starting point. While we do not see the starting point the man moving the plane moves to the other store showing that motion has occured Describe what is a reference point. Suppose the man is in Ali Alsendi motion what might he use as a reference point as he moves from one house to another the starting point you choose to describe the location or position of an object if the vehicle is straight with the other vehicle when parking a driver can straten some part of the vehicle with the roadway like one family going to their grandpa's house your going straight to it that's how reference point they moved to one point to another house Group 6: Forces What is force? What is force measured in? Identify friction as an example of a contact force and gravity as a non-contact force. Analyze the image below, explain what type of force and the effect of the force exerted onto the object. What is force? Force is a push or a pull effect that causes an object to move faster or slower changer direction change size or shape by. Maryam Ghuloom What is force measured in? Force is measured in neutrons also known as (N) and the unit of the force is (F) = (N) Identify friction as an example of a contact force and gravity as a non-contact force Contact forces are forces that require direct physical contact between two objects. Non-contact force is when something is not in contact but still uses force, such as gravity Analyze the image below, explain what type of force and the effect of the force exerted onto the object. In this image a push force is being exerted onto the whiteboard which symbolyes work being done because the person is exerting a push force onto the whiteboard and the whiteboard is in motion. Group 7: Work Work done: What is work? Identify the equation (formula) that links work, force and distance. Is work done when you hold a heavy object for a long time? Why or why not? In the image shown above suppose the car is moving. Is work done by Jim? Give a reason for your answer. Use mathematical reasoning to determine if work is done on an object. E.g Mr. Ahmed is pushing a stalled car with a force of 50 N along 12 m on a straight road. Calculate the work done by the person. Question 1 What is Work:Work is using a force to move an object a distance, when both the force and the motion of the object are in the same direction Question 2:Identify the equation (formula) that links work, force and distance. Answer: W = F x D Question 3: Is work done when you hold a heavy object for a long time? Why or why not? Answer: work is not being done because if you hold a heavy object for a long period of time there is no force and there is no motion onto the object Question 4: In the image shown above suppose the car is moving. Is work done by Jim? Give a reason for your answer. Answer: there is no work being done because Jim is not exerting force and there is no motion onto the object. Bader AlRadhi: Question 4:Use mathematical reasoning to determine if work is done on an object. E.g Mr. Ahmed is pushing a stalled car with a force of 50 N along 12 m on a straight road. Calculate the work done by the person. W=FxM = 50N x 12M = 600J
