No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.

What doesn't change with changes in gravity?
The mass of an object does not change with changes in gravity. Mass is a measure of the amount of matter in an object and is constant regardless of the strength of the gravitational field acting on the object.
How is the density of a pure substance affected if the mass and or volume are changed?
The density of a pure substance remains constant regardless of changes in mass or volume. Density is a physical property that is inherent to a substance and is calculated as mass divided by volume. As long as the substance remains the same, the density will not change.
Does a substance change density if it changes physically?
No, the density of a substance remains constant regardless of any physical changes it undergoes. Density is defined as mass divided by volume, and this property does not change with physical alterations like changes in shape or state.
Does the mass change as a substance goes through a phase change?
Mass is conserved. Volume changes slightly, so density changes as well, but mass remains the same.
How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
