20 Questions
Who discovered Charles' law?
Jacques Charles
What is Charles' law?
When gas pressure remains constant as the temperature increases, the volume of the gas will also increase.
What is the relationship between gas volume and temperature according to Charles' law?
Directly proportional
According to the kinetic molecular theory, what happens to gas particles when they are heated?
They move faster and spread out
What is the concept behind heating a gas in a hot air balloon?
Increasing the temperature of the gas particles to make them move faster and spread out, thus increasing the volume of the gas and causing the balloon to lift
What is the difference between the densities of two cubes filled with gas molecules of the same volume but different masses?
The cube with more molecules will have a higher mass and density than the cube with fewer molecules
What is the relationship between the temperature of a gas and its volume, according to Charles' Law?
According to Charles' Law, if the pressure of a gas is held constant, as the gas is heated, its volume will increase. The reverse is also true: cooling a gas will cause its volume to decrease.
What is the equation that represents Charles' Law?
$V_1 / T_1 = V_2 / T_2$
What is absolute zero and how was it discovered?
Absolute zero is the temperature at which a gas has a volume of zero. It was discovered by Lord Kelvin, who measured the volume of different gases at different temperatures and extrapolated the data to find that the volume would be zero at a temperature of approximately -273 degrees Celsius.
What are the units for temperature that must be used in the equation representing Charles' Law?
The units for temperature must be Kelvin (K) for the equation $V_1 / T_1 = V_2 / T_2$ to work.
In the example given, what is the final volume of the balloon when it is put in the freezer?
The final volume of the balloon when it is put in the freezer is 0.887 L.
In the second example given, what is the final volume of the bag of potato chips when taken outside on a hot summer day?
The final volume of the bag of potato chips when taken outside on a hot summer day is 500 mL.
What is Charles' Law?
Charles' Law states that the volume of a gas is directly proportional to the temperature of a gas. The equation commonly used is $V_1 / T_1 = V_2 / T_2$.
What does it mean when the particles of a gas move closer together?
When the particles of a gas move closer together, the gas becomes more dense.
What happens to a hot air balloon when the air inside cools?
When the air inside a hot air balloon cools, the particles slow down and move closer together, causing the balloon to sink.
What is the initial volume and temperature in the given example?
The initial volume is 500 mL and the initial temperature is 293 K.
What is the final temperature in the given example?
The final temperature is 311 K.
What is the equation used to solve for $V_2$ in the given example?
The equation used to solve for $V_2$ is $V_1 / T_1 = V_2 / T_2$.
What is the value of $V_2$ in the given example?
$V_2$ is equal to 531 mL.
Explain why the volume of a gas increases as it is warmed up.
As a gas is warmed up, the particles speed up and get farther apart, which causes the container to expand.
