I see you're working on number 6.
But the answer is Latent Heat.
Water changes from a liquid phase to a gaseous phase when it is boiled.
Phase changes of water, such as melting, freezing, boiling, and condensation, are caused by changes in temperature and pressure. When water reaches its melting or boiling point, the intermolecular forces break or form, resulting in a change in the water's molecular arrangement and a transition to a different phase.
When water reaches its boiling point (212oF), its phase changes to gas through the process of evaporation.
The phase of water changes in response to temperature and pressure. When water is heated, it changes from a solid (ice) to a liquid (water) at its melting point, and then to a gas (steam) at its boiling point. Conversely, when water cools down, it transitions from a gas to a liquid to a solid.
The process by which water vapor changes to a solid is called deposition. This occurs when water vapor in the air changes directly into ice without passing through the liquid phase. This can happen when the temperature and pressure are low enough for the water vapor to bypass the liquid phase and form ice crystals.
Water changes from a liquid phase to a gaseous phase when it is boiled.
Changes in both temperature and pressure induce phase changes in water (and all other materials!).
Fahrenheit Scale is the temperature scale that is not directly or indirectly based on the phase changes in water. Another similar temperature scale is Celsius Scale.

When water reaches its melting or boiling point, the intermolecular forces break or form, resulting in a change in the water's molecular arrangement and a transition to a different phase.
When water changes from liquid to gas, this phase is known as vaporization.
When water changes from liquid to gas, this phase is known as vaporization.
solid,liquid and gas
Water changes phase.
When water changes from one phase to another (e.g., solid ice to liquid water or liquid water to water vapor), energy is either absorbed or released. This energy is used to break or form intermolecular bonds between water molecules without changing the temperature.
For example after phase changes.
Liquid to solid
Physical, as it remains water.
