Study Notes
- Matter is anything that occupies space and has mass.
- States of matter include solid, liquid, and gas.
Solids
- Solids are firm and hard with a definite shape.
- Examples of solids include stones, firewood, and cooking pots.
Liquids
- Liquids have no fixed shape, taking the shape of their container.
- Examples of liquids include water, juice, and soda.
Gases
- Gases have no fixed shape and are usually lighter than solids and liquids.
- Air is an example of a gas.
Investigating Properties of Matter
- Matter can change states depending on temperature changes.
Experiment 1: Water in the Solid State
- Aim: To demonstrate the properties of water in the solid state.
- Water in its solid state (ice) is colourless, firm when pressed, and maintains its shape regardless of the container.
- Solid ice floats in liquid water and melts into liquid water when exposed to warmer conditions.
- Conclusion: Water in its solid state is firm, retains a definite shape and volume, and does not flow like liquid water.
Experiment 2: Water in the Liquid State
- Aim: To demonstrate the properties of water in the liquid state.
- Water in its liquid state has no colour, taste, or smell.
- It has no definite shape, taking the shape of the container, but maintains a fixed volume.
- Water flows freely from one place to another.
- Conclusion: Water in its liquid state has no fixed shape but maintains a definite volume.
Experiment 3: Water in the Gaseous State
- Aim: To demonstrate the properties of water in a gaseous state.
- As the temperature rises to 100 °C, water boils and produces water vapour.
- Water vapour has no colour or smell and cannot be touched.
- It has no fixed shape or volume and spreads out to fill any available space.
- When cooled, water vapour turns back into liquid water.
- Conclusion: Water in its gaseous state has no fixed shape or volume, but when it cools down, it changes back into liquid water.
Experiment 4: Changing Gas to a Liquid State
- Aim: To demonstrate the changing of gas to liquid state.
- Liquid water boils, and water vapour escapes.
- The water vapour condenses into small water droplets when it comes into contact with a cool surface.
- Water vapour changes back into liquid water when it cools.
- Conclusion: The experiment demonstrated the process of changing gas (water vapour) into liquid water through condensation.
Condensation
- Condensation is the process of changing gas to liquid state.
- The vapour condenses and appears as mist which turns into a liquid state.
Freezing Point of Water
- Water freezes when it reaches a specific temperature.
- The freezing point of water is the exact temperature at which a liquid freezes into a solid.
- The freezing point enables uses such as preserving food, to slow bacterial growth and prevent spoilage of foods.
Experiment 5: Freezing Point of Water
- Aim: To demonstrate the freezing point of water
- When the temperature of water drops to 0 °C, the water begins to freeze.
- Water freezes at a specific temperature as the freezing point.
- 0 °C is the temperature at which water changes from liquid to solid.
Boiling Point of Water
- Water boils when it reaches a specific temperature.
- The boiling point is the exact temperature at which a liquid boils and turns to water vapour.
- The boiling point ensures safe drinking water, and cooks food well.
Experiment 6: Boiling Point of Water
- Aim: To demonstrate boiling point of water
- When water reaches 100 °C, it boils.
- This temperature is known as the boiling point of water.
- Conclusion: The experiment showed that the boiling point of water is 100 °C.
Celsius
- Celsius is a unit of measurement for temperature based on the freezing point of water at 0 °C and the boiling point of water at 100 °C.
Degree
- A degree is a unit of measurement used to express how hot or cold something is.
Fahrenheit
- Fahrenheit is a unit of measurement for temperature based on the freezing point of water at 32 °F and boiling point of water at 212 °F
Temperature
- Temperature is a measure of how hot or cold something is.
