|---|---|---|---|---|---|
| What is matter? | Anything that takes up space and has mass
🗑
|
||||
| What is mass? | The amount of matter an object contains
🗑
|
||||
| List the 3 states of matter | Solid, Liquid, Gas
🗑
|
||||
| When something is solid the particles are________ | packed tightly together so they vibrate
🗑
|
||||
| When something is liquid the particles are________ | moving and slide around one another. Have more energy than solids.
🗑
|
||||
| When something is a gas the particles are__________ | spread far apart, filling any space they're in. Have more energy than liquid
🗑
|
||||
| What is compression of gases? | Gas particles are spread far apart, compressing them forces them to be closer together in a smaller space
🗑
|
||||
| List the 5 properties of solids | fixed mass, fixed volume, fixed shape, does not flow, does not compress
🗑
|
||||
| List the 5 properties of liquids | fixed mass, fixed volume, no fixed shape, does flow, does not compress
🗑
|
||||
| List the 5 properties of gases | fixed mass, no fixed volume, no fixed shape, does flow, does compress
🗑
|
||||
| What is diffusion? | Diffusion is the spreading out of particles to fill the space they're in
🗑
|
||||
| Give two examples of diffusion | Perfume and Cooking
🗑
|
||||
| List 3 things that effect how quickly diffusion occurs | temperature (higher temperature, quicker diffusion), size of particles (smaller particles move quicker), state of matter (quickest in gases)
🗑
|
||||
| What word describes a change from a solid to a liquid? | Melting
🗑
|
||||
| What word describes a change from a liquid to a gas? | Evaporation/boiling
🗑
|
||||
| What word describes the change from a gas to a liquid? | Condensation
🗑
|
||||
| What word describes the change from a liquid to a solid? | Freezing
🗑
|
||||
| What is melting point? | The temperature at which a substance melts
🗑
|
||||
| What is freezing point? | The temperature at which a substance freezes
🗑
|
||||
| What is evaporation? | Liquid particles are heated and become more energetic. They spread out to form a gas.
🗑
|
||||
| What is boiling point? | The temperature at which a liquid changes to a gas
🗑
|
||||
| What is condensation? | Cooling a gas takes energy from the particles so they slow down moving and come closer together to form a liquid
🗑
|
||||
| List the 5 steps of the product life cycle | Extraction, manufactoring, packaging and distribution, product use, end-of-life disposal
🗑
|
||||
| What is a carbon footprint? | The total greenhouse gas emissions caused by an organisation, event, product or individual
🗑
|
||||
| What is a physical change? | Matter changes shape or state but no new substance is formed. Easy to reverse
🗑
|
||||
| What is a chemical change? | A new substance is formed. not easy to reverse.
🗑
|
||||
| What is law of conservation of mass? | Matter cannot be created or destroyed but can change from one form to another
🗑
