Question

A student observed that during change of state ,temperature remains constant i.e. ice at zero degree celsius produces at water at zero degree celsius .Does it means that zero degree celsius ice and zero degree celsius water have the same energy .Give reason​

Answer 1

Answer :

Yes it is true that during the change of state temprature remains constant. As the heat absorbed by substance underwent into changing the state and increasing the random motion of molecules. So the temperature remains constant during the change of state.

Ice is more effective in cooling than water at the same temperature because ice can absorb latent heat as well as the heat energy in order to attain room temperature. Water at 0 C can absorb heat energy only to attain the room temperature.
