2‌kg of ice at −20∘C is mixed with 5‌kg of water at 20∘C in an insulating vessel having a negligible heat capacity. The final mass of water in the container is
(The specific heat capacities of water and ice are 1‌kcal‌kg−1‌‌∘‌C−1 and 0.5‌kcal‌kg−1‌‌∘‌C−1 respectively, the latent heat of fusion of ice is 80‌kcal‌kg−1 )
