Answer 4

Liquids

Question 5

-no definite shape of volume
-attraction between the molecules of a gas is very weak.

Answer 5

Gases

Question 6

The states of matter can be changed by adding or removing heat energy. As heat is applied to a solid it ____, this happens because the heat is causing the bonds between molecules to loosen, allowing them to flow freely.

Answer 6

melts

Question 7

the temperature when a solid becomes a liquid. It boils and evaporates, turning into a gas as the motion of its molecules increases.

Answer 7

melting point

Question 8

Boiling Point

Answer 8

The point when a liquid becomes a gas, when heat is removed from a gas , the motion of its molecules decreases and it turns into a liquid.

Question 9

The temperature when a gas becomes a liquid, When heat is removed from a liquid, the motion of its molecules slows until it solidifies.

Answer 9

Condensation point
