In a closed system as a substance changes from a liquid to a gas what is happening?

The particles of the liquid are colliding with each other at a rate/force that allows them to separate considerably further than when they were a liquid, thus making them a gas.
The temperature at which this occurs can vary depending on the material in question, and the pressure of the container. The presence of substances that would "lower" the boiling temperature (such as boiling stones) do not actually lower the material's boiling temperature, but rather allow the temperature to spread more smoothly, and thus cause it to boil faster with the same heat input.
Even though the individual particles still "boil" at the same temperature as before, the more even distribution of heat causes them all to reach boiling point much faster than before.

A substance changes from a solid to a liquid?
You mean if a substance can go from solid to liquid? Of course, take the ice cubes out of the freezer and you'll see it happening. Do you mean that when such process occurs, does the substance changes? No, only the grouping and movement of particles in it.

vaporization
What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.

When a substance changes from a liquid to solid it is...?
When a substance changes from liquid to solid is called freezing.
What is the point at which a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at its melting point
What is happening to the molecules of a substance when boiling takes place?
The molecules vibrate faster until so much thermal energy is generated that the substance changes from a liquid to a gas.

What happens when substances goes through a phase change?
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
