Question

Under what condition,does a substance not show any change in its temperature even when it is being heated?

Answer 1

When a substance is heated, it will not show any change in temperature, if the heat is absorbed by the particles of that substance. When this happens, the kinetic energy of the particles will become more and they become free from the intermolecular force of attraction. This extra heat absorbed by the substance of the particles is called the latent heat. Latent means hidden.

Answer 2

"A substance does not show any change in its temperature even when it is heated because the heat energy involves in kinetic energy therefore there will be no change in the temperature but only physical state of substance will change.

  During the phase change between solid, liquid, and gases, when we heat the substance then also the temperature will not change. This is because when we heat the substance, the heat energy provides the kinetic energy to the particles.

  This kinetic energy allows the particles to move and change the "physical state" from "solid to liquid" or "liquid to gas"."
