What has to be added to change one state of matter to another?

Answer 1

heat

Most often: energy

Remove energy from a gas and it usually liquefies, remove energy from a liquid and it usually solidifies.

These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.

Answer 2

Nothing is added to matter to change its state. The behavior of the particles (molecules) determines its state of matter.

The particles in a solid are tightly packed (particles are locked into place)

The particles in a liquid are close together (particles can slide pass each other)

The particles in a gas are well separated (articles can move pass each other and change volume)

Answer 3

Energy must be added or removed to change one state of matter to another. For example, adding heat can melt a solid into a liquid, and then adding more heat can vaporize the liquid into a gas.

Answer 4

A lot of energy. For example, to go from a liquid to a gas, you have to add enough energy to get to the fusion point, then add the energy equivalent of the latent heat of vapourization.

Answer 5

acid have to be taken for the matter to change

Answer 6

The answer to this would be energy. When energy is removed from water, it changes its state to become ice. the same concept applies to adding energy. the water boils and becomes water vapour.

Answer 7

This is a thermal energy.

Answer 8

energy.
