A mass m of water is at a temperature of 290K. The specific heat capacity of water is c. Ice, at its melting point, is added to the water to reduce the water temperature to the freezing point. The specific latent heat of fusion for ice is L. What is the minimum mass of ice that is required

17 mc/L

Explanation:

We habe heat that is taken by the ice for it to melt to be equal to the heat given by water.

ML = mc(290K - 273K)

ML = mc 17

Then we divide through by L

M = 17 mc/L

Please note that 273k as we have used in thIs solution is the temperature at which we can have water to freeze

Therefore the minimum mass of required ice = 17 mc/L
