When a substance changes from liquid to gas, it absorbs heat energy, causing the particles to gain enough energy to break free from their fixed positions and move more freely. This transition is known as vaporization or evaporation. Conversely, when a substance changes from gas to liquid (condensation), it releases heat energy, causing the particles to come closer together and form a liquid.

What happens when a pure substance undergoes a chemical changes?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What happens to a substance during changes between a liquid and gas?
Vaporation takes place when the particles in a liquid gain enough energy to move independently forming a gas. if anyone has more info please add it. Thank you
What happens to a substance in physical change?
it means figure it out yourself!
What happens to molecular energy when a substance changes states?
The molecular energy will usually increase or decrease, depending on the exact situation.
What happens to a substance during changes between solid and I gas?
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
What happens to a substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to substance during changes between solid and liquid?

What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
What happens when one substance changes into one or more new substances?
it just creates a new substance!
