Question 8

What is the change of state from gas to liquid?

Answer 8

Condensing

Question 9

What is the change of state from liquid to solid?

Answer 9

Freezing

Question 10

What is the change of state from gas to solid?

Answer 10

Deposition

Question 11

What type of energy connects the bonds which control the changes of state?

Answer 11

Heat
(More heat = less bonds)

Question 12

How do the changes of state occur?

Answer 12

Energy must be transferred, by heat.
—>Particles gain energy, which breaks bonds (melting)

Question 13

What is this heat energy needed to do?

Answer 13

To make/break down the attractive forces between particles

—> At melting/boiling points, energy is being exchanged so the attractive forces can be made/broken
