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#?

Question

Luna Chen · Accepted Answer

We need the #"specific heat of ice......"# And also we need the #"latent heat of fusion of ice"#, and also we need the #"specific heat of water"#. You have supplied NONE of these constants.

undefined The energy required to heat a 1 g block of ice at -10°C to 1 g of water at +10°C is calculated using the specific heat capacity of ice and water, as well as the heat of fusion for ice.

1. First, calculate the energy needed to raise the temperature of the ice from -10°C to 0°C using the specific heat capacity of ice.
2. Next, calculate the energy needed to melt the ice into water using the heat of fusion for ice.
3. Then, calculate the energy needed to raise the temperature of the water from 0°C to +10°C using the specific heat capacity of water.
4. Add these three calculated energies together to find the total energy required.

The specific heat capacity of ice is 2.09 J/g°C, the specific heat capacity of water is 4.18 J/g°C, and the heat of fusion for ice is 334 J/g.
