Given,
Latent heat of ice,Lice=336 kJ/kg
Specific heat of water, Swater=4.2 kJ/kg oC
Mass of water, Mwater=0.1kg
Mass of ice, Mice=0.02kg
If final temperature is Tf
Heat Loos from steam = heat gain by ice
MwaterSwater(30−Tf)=MiceLice+MiceSwater(Tf−0)
Tf=MwaterSwater×30−MiceLice(Mice+Mwater)Swater
Tf=0.1×4.2×30−0.02×336(0.1+0.02)×4.2
Tf=11.6oC
Final temperature of mixture is 11.6oC
