As a substance transitions from liquid to gas, the molecular motion increases. In the liquid state, molecules move more freely but are still close together. When the substance becomes a gas, the molecules move even more rapidly and are much farther apart.
A substance that will change from a solid to a liquid is called a melting substance. This process is known as melting, where the solid substance absorbs heat energy and transitions into a liquid state.
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
Yes, sublimation is a physical change in which a substance transitions directly from a solid to a gas without passing through the liquid phase.
The change of phase from a vapor to a liquid is called condensation. This process occurs when a substance loses heat energy and transitions from its gaseous state to its liquid state.
The melting point is a physical property that indicates when a liquid will change into a solid. It is the specific temperature at which a substance transitions from a liquid state to a solid 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.

The phase change in which a substance changes from a gas to a liquid is called condensation. This occurs when the gas loses energy, typically through cooling, and transitions to a liquid state.
As a substance changes from a solid to a liquid, the molecular motion increases as the intermolecular bonds break and the molecules can move past each other more freely. When a substance transitions from a liquid to a gas, the molecular motion increases further as the molecules have enough energy to overcome intermolecular forces entirely and move independently.

A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
A phase change is a physical property where a substance transitions from one state of matter to another, such as from solid to liquid, liquid to gas, etc.
When a substance changes state, its density can change. For example, when a substance transitions from a solid to a liquid state, its density usually decreases. Conversely, when a substance transitions from a gas to a liquid state, its density typically increases.
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.

No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
