The atoms that make up the matter begin to move.
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
When heat is added to a pure phase of matter, the kinetic energy of the particles in that phase increases. This increase in kinetic energy causes the particles to move faster and the temperature of the phase to rise.
Add heat.
No, air is matter because it takes up space and has mass. Heat, on the other hand, is not matter but rather a form of energy that can be transferred between objects.

If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).

You can raise an object (potential energy), make it move (kinetic energy), or add heat to it (heat energy, a.k.a. thermal energy).
add or take away heat.
To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.

If the matter is in a liquid state, add heat to turn liquid to vapor. Remove heat to form a solid. If it is in the form of a vapor, remove heat to form a liquid, and remove more heat to form a solid. If it is in the form of a solid, add heat to turn it into a liquid. Add more heat to turn into a vapor.
To change the state of matter, you need to add or remove energy. For example, to change a solid to a liquid, heat is added to increase the temperature until it reaches the melting point. Likewise, to change a liquid to a gas, heat is added to increase the temperature until it reaches the boiling point.
Technician A is incorrect. The latent heat of fusion is the amount of heat required to convert a solid into a liquid at its melting point. To convert a liquid to a gas, you would need to add the latent heat of vaporization.
heat affects matter by melting frozen items. example: ice + heat= matter
