Answer 1

When some solid melts, the temperature of the object remains the same.

This is because the heat energy provided in its transformation of the state is latent heat.

The latent heat provides the energy to the solid to change into a liquid, therefore, there is no overall change in the temperature of the solid.

Answer 2

Whem soils melts no change in temperature observed.

The heat provided to the soil get used up by the solid to over come the force of attraction between their particles.

Hence, there all provider heat get used up. Thus , no change in temperature is observed.
