When temp. of solid increases matter loose it capacity and melts uh can see best example of water nd ice........!!
when temp. of solids increases , the kinetic energy between the particles of solid increases resulting in the break down of solids..... further increasing will result in more kinetic energy and the particles will become more volatile...this results in the chage in state of change in matter
so in the two answers.... i feel avni's answer is the best
thankyou utkarsh !!
