Answer 1

Answer:

when there is a change in state of matter , the temperature remains constant.

For example, when we give heat to ice cubes to convert it into water , the initial temperature of ice cubes is zero degree Celsius. The temperature remains constant ( 0℃) until all the ice cubes get converted into water. Once the all ice cubes are converted into water , the temperature starts rising.

The reason behind the constant temperature is latent heat.

Answer 2

Answer:

The temperature remains constant as the heat is used up in changing the state by overcoming the forces of attraction between the particles.  Its temperature does not rise until the entire solid is converted into liquid. This heat energy gets hidden into the contents and is known as the latent heat.
