Question

The diagram below shows the different phase transitions that occur in matter.

Which arrow would most likely represent the phase change that involves the same amount of energy as arrow 1?

2

3

4

5

Answer 1

The amount of energy required in the transition from liquid to gas is equivalent to the transition from gas to liquid, so arrow 4.

Answer 2

The answer is: arrow 4 involves the same amount of energy as arrow 1.

The amount of energy required in the transition from liquid to gas is equivalent to the transition from gas to liquid.

The process by which a substance moves from the liquid state to the gaseous state is called boiling.

For example, phase diagram of water:

Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor).

Condensation is phase change process in which the water changes from a gas to a liquid, the vapor becomes a cloud.
