Answer:

1. When a substance turns changes from a solid or liquid into a gas, the process is called vaporization

2. The temperature at which solid and liquid states coexist together is called the Melting point.

Explanation:

3. Increasing pressure usually increases the boiling point of a liquid. A way to think about it is that the molecules of the liquid need more energy to break into the gas phase when the more molecules are hitting the surface of the liquid with more energy.

4. Dry Ice , Menthol , Camphor

5. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.

6. The temperature remains constant during the change of state because the heat energy which is supplied to change the state of matter is used in breaking the intermolecular forces and other attractive forces. ... Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed.
