A vessel of negligible heat capacity contains 5-0 kg of water at `50^@`C. If 5.0 kg of ice at `0^@`C is added to it, find : (i) heat energy imparted by water in fall of its temperature from `50^@`C to `0^@`C, (ii) mass of ice melted, (iii) final temperature of mixture, and (iv) mass of water at `0^@`C in mixture. Given : specific heat capacity of water = 4200 J `kg^(-1) K^(-1)`, specific latent heat of ice = 336 kJ `kg^(-1)`.
