Question

why does the ice cream appear cooler to the tooth than the ice cold water?​

Answer 1

It's because the fact that water has latent heat of fusion present in it. But ice-cream is in solid form; i.e. it has released its latent heat of fusion of while coming in solid state. So due to less energy of ice-cream in comparison to that of water; ice-cream appears cooler to mouth than that of water at 0oC.

Answer 2

Explanation:

Ice cream appears more cooler to the mouth than the water at zero degrees celsius because ice cream absorbs latent heat as well as the heat energy in order to attain room temperature....Thus water absorbs less amount of energy from the mouth as compared to ice cream.
