6. What is melting point? Image: 1334841 1398397616827 (image/gif)	The temperature at which a solid will melt into a liquid.
7. What is evaporation? Image: Evaporation (image/png)	The process in which heat causes liquid water to evaporate.
8. Why do clothes dry faster on hot days? Image: Clothes Dryer Machine 1 (image/jpeg)	The water particles have enough energy from the sun to break free.
9. What is sublimation? Image: Waterphases (image/png)	When a substance changes to it's third stage without having to go into the second one.
10. What is boiling? Image: Act Quickly And Calmly When Suffering A Boiling Water Burn (image/jpeg)	When a liquid is heated and it results in bubbling.
11. What is boiling point? Image: Boilingpoint (image/gif)	The temperature at which a liquid boils.
12. How are bubbles formed? Image: Can Stock Photo Csp14867036 (image/jpeg)	By evaporation of pockets of liquid deep inside the liquid itself.
13. What is the boiling point of a substance? Image: Sealed2 (image/gif)	It's the temperature at which it changes from a liquid into a gas.
14. What happens when a substance is cooled? Image: 4e8909cebe37f6dd46758b1f5d3e55e1899e159b (image/gif)	It looses its energy and the particles move more slowly than before.
15. What happens to a substance if enough heat is removed from a substance?	When all of the substance's heat is removed the substance will eventually change state.
16. What is freezing? Image: Freezing Ftr (image/jpeg)	When heat is lost and liquid changes into a solid.
