This change occurs when a liquid substance turns to solid

When solid turns to liquid, this means that the soldi sample has reached its melting point.

In this state, boiling is a requirement. It is at boiling point that heat energy breaks the molecular bond of liquid molecules, causing it to turn to gas.

It is the process that requires extraction of heat to turn vapor back to its liquid form.

With heat, a solid substance can turn to gas easily without passing through the liquid state.

It is the opposite of sublimation and occur when heat is extracted from a gaseous substance.

It is the measure of average kinetic energy of particles in a given body.

It is the sum of the kinetic and potential energy of particles.

It is not an intrinsic characteristic of a body. Its presence and direction of flow depends on the difference between the temperature of a body and its environment.

It is the amount of heat that will changhe the state of a substance at a specific temperature.
