Answer 1

Latent heat is used up in changing the state by overcoming the force of attraction between the particles.                                               

Detailed Answer :  The temperature remains constant as the heat is used up in changing the state by overcoming the forces of attraction between the particles. For example, a solid melts on heating. 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.
