Question

does the temperature of a substance change while it changes its state ?explaun why or why not​

Answer 1

Answer:

During change of state (from solid to liquid, gas to liquid, etc.) the heat energy that is supplied to the substance is used for the change of state and not to increase the kinetic energy of the molecules (that contributes to the temperature of the substance), so the temperature remains constant.

Answer 2

Answer:

Physical conditions like temperature and pressure affect state of matter. ... When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
