Why does the temperature not change during a phase change?

Answer 1

During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.

Answer 3

When a substance undergoes a phase change, such as from a solid ice cube to water, there is a change in heat energy. However, this change in heat energy does not cause a change in temperature because the heat energy is utilized to decompose the bonds between molecules.

Answer 4

The basic idea is that energy is required just to change the phase. When (for example) a solid is changed to a liquid, that, by itself, requires energy, apart from the energy required to increase the temperature. By the way, some substances have a well-defined transition temperature (from solid to liquid), while others soften gradually, while the temperature increases.

Answer 5

Because the substance is using all of it's energy to change phases it doesn't have any energy to spare for temperature. Once it is all changed into the new phase the energy will turn into heat and the temperature will begin to change again.

Answer 6

the temperature of a substance doesnt change when it undegoes a phase change because the energy that is going into the substance is being used to change the phase of the substance, it doesnt increase the temperature. an example of this would be water. when it is at 32 degrees it is frozen, and it crystalizes. but when it melts. all of the energy is being used to break apart the crystals that form the ice, none of the energy is increasing the temperature.

Answer 8

Temperature is constant, because during a phase change substance absorbs heat energy and converts it to potential energy.

Answer 9

Because during a phase change kinetic energy doesnt change

Answer 10

any phase change process is an isothermal process,where the change of heat takes place at a constant temperature
