Sublimation
When particles heat up they gain ______ energy.
Kinetic
Temperature is a measure of the average _____ Kinetic energy of all the particles in a substance.
Kinetic
Why does a balloon deflate when you put it in the freezer over night
The particles lose energy so they take up less space and get closer together
Why happens to the water vapour as it condenses on the same side of the beaker
The particles slow down and get closer together and form sting LINKS and chafe to a liquid
When a material heats up the particles that material moves _______ and get ______ _____ this makes the material _____ less
Faster
Further apart
Less
Solids
- Strong forces of attraction
- In a fixed regular arrangement
- Don’t have much energy
- Vibrate in fixed positions
Liquids
- Weaker forces of attraction
- Close irregular arrangement
- More energy than solids
- More in random directions at low speeds
Gases
- No forces of attraction
- Have the most energy
- Free to move
- Travel in random directions at high speeds
What happened when you heat a substance up
You give the particles more kinetic energy
They vibrate or move faster.
Conduction of heat occurs
Mainly in solids
