# How much energy is required to heat a 1*g block of ice at -10 ""^@C to give a 1*g mass of water at +10 ""^@C?

We need the $\text{specific heat of ice......}$
And also we need the $\text{latent heat of fusion of ice}$, and also we need the $\text{specific heat of water}$. You have supplied NONE of these constants.
