Question 10

When a solid turns to a liquid and a liquid turns to a gas, what is happening to the energy in this process?

Answer 10

The energy is absorbed

Question 11

When a gas turns to a liquid and a liquid turns to a solid, what is happening to the energy in this process?

Answer 11

Energy is released

Question 12

What is dry ice made up of?

Answer 12

Carbon dioxide

Question 13

During a change of state, what happens to the temperature of the particles?

Answer 13

It remains constant as the heat energy is absorbed in the state change

Question 14

In a temperature/time graph what should you include?

Answer 14

The place where states change

Question 15

When a solid is heated, why does temperature remain constant during state change?

Answer 15

Because when heated the particles gain energy, however this energy is needed to overcome the forces holding the particles together, so the temperature remains constant. Once all forces are broken, the temperature will increase again
