Take 150g of Ice in a beaker and suspend a Laboratory Thermometer so that the bulb is in contact with ice. Start heating and note the temp. When the ice starts melting, finally note the temp when all the ice is completely melted.
U observed that there is no change in the temp. During the change of state from solid to liquid. As we know that for the change of state, heat is required thus substances absorb heat during melting without change in its temp.
I hope this answer is helpful !!
Plz nark me in the brain list.
