Answers
melting of ice absorbs heat but still is a physical change because :
No new substance formed : water is obtained which is the liquid state of water.
it can be reversed : the water so obtained can be conversation to ice by freezing
NO ENERGY CHANGE : WHEN ICE ABSORBS HEAT TO FORM WATER THE SAME AMOUNT OF HEAT IS RELEASED WHEN WATER IS FREEZED . SINCE THE SAME AMOUNT OF HEAT CAN BE OBTAINED BACK , THERE IS CONSIDERED TO BE NO ENERGY CHANGE .....
