What are the observable changes in freezing water?
liquid to solid
When a gas or liquid is heat it's mass?
Heating gasses or liquids has no effect on their masses.
Does the composition stays the same or pure substance?
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.

What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
Are the melting and freezing of a substance the same?
