Question

Ice cream appears colder to the mouth than water at zero degree celsius give reason

Answer 1

I hope you know the concept of latent heat.
it is the hidden heat enery which is utilised in the change in state.

In this case the water has additional latent heat of fussion and hence it feel hotter than icecream even in the same temperature

Answer 2

Water shows a property of absorbing and releasing a fixed amount of energy just as any other liquid.

This fixed amount of energy is known as latent heat

It is of two types

Latent heat of fusion

AND

latent heat of vaporisation

During conversion of ice into water , ice absorbs some amount of energy from the surrounding for conversion of state known as latent heat if fusion..we can't measure this energy but it exists.

So when heat is absorbed surrounding becomes cool


HENCE SINCE ICE RELEASES LATENT HEAT IT APPEARS COLDER.
