Answer:
=1.36kg
Explanation:
First heat is absorbed to melt the ice- latent heat of fusion of ice then heat is absorbed to raise the temperature to 373K
The specific heat capacity of water is 4.187kJ/kg/K while the latent heat of fusion of ice is 2230kJ/kg/K.
Letting the mass of the ice to be =x
x×2230kJ/kg/K + x×4.187kJ/kg/K×100K= 3600kJ
2230x+418.7x=3600
2647.8x=3600
x=1.36 kg
