The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion and that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.
When ice melts, it is converted to the liquid water at 0 °C by absorbing latent heat of fusion. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, which is absorbed from your surrounding (mouth). Your body releases this heat and that's why it feel colder
In case of water this “extra heat” in form of latent heat is not released, thus water appears to be warmer compared to Ice at same temperature.
