Four cubes of ice at -10°C, each 1 gm, are taken out from the refrigerator and put in 150 gm of water at 20°C. Find the temperature of water when thermal equilibrium is attained. Assume that no heat is lost to the outside and the water equivalent of the container is 46 gm. (Specific heat capacity of water =1 cal gm-1 °C-1, specific heat capacity of ice =0.5 cal gm-1 °C-1, latent heat of fusion of ice =80 cal gm-1 °C-1.)
