Question

When a solid melts, it's temperature remains the same,so where does the heat energy go?
Explain in your own words.

Answer 1

this is because the heat energy is used up in overcoming the force of attraction between the particles. this hidden heat is called latent heat

Question:-)When a solid melts, it's temperature remains the same,so where does the heat energy go?

Answer:-)
The heat energy gets converted into kinetic energy to increase the brownian motion of the particles in the salid. 

Thus, they vibrate with greater amplitude and break free of the intermolecular forces of attraction and the solid gets converted into liquid. So, no change in temperature is observed.
