1. What happens when you cool a gas?

  • It condenses into a liquid Particles lose kinetic energy meaning and are brought closer together by forces of attraction, making them clump together.
  • The gas instantly wears black sunglasses. It's cool you know.
  • It condenses into a solid: Particles lose kinetic energy and become completely still.

2. What happens to the particles when you freeze a liquid?

  • Particles gain kinetic energy vibrating faster and faster until they completely brake the forces of attraction between them.
  • Particles lose kinetic energy allowing the forces of attraction to hold them together. They then rearrange themselves into a regular pattern, disabling them from sliding past one another.
  • Particles lose kinetic energy meaning forces of attraction bring them close together. This means particles clump together.

3. What happens when you change a solid to a liquid?

  • Particles explode.
  • Particles gain kinetic energy which causes them to vibrate faster and allows them to slide past one another.
  • Particles lose kinetic energy moving further apart and causing them to clump together.

4. When you cool a liquid its.....

  • .........Particles lose kinetic energy but are still able to move past each other.
  • ......Particles arrange into a regular pattern as a result of losing kinetic energy. Forces of attraction between the particles hold them together.
  • .....Particles self combust.

5. How do you change a solid to a gas?

  • Heat the solid until it sublimes.
  • Heat the solid until it melts
  • Steal some of the solids particles.
