Question

(c) A thermos flask of negligible heat capacity
contains 100 g of ice and 30 g of water. Calculate
(i) The mass of steam at 100°C needed to
condense in the flask so as to just melt the ice;

(ii) The amount of water in the flask after
condensation.
bu
(Specific latent heat of vapourisation of
steam = 2260 J/g, Specific latent heat of
fusion of ice = 336 Jlg, Specific
heat
capacity of water = 4.2 J/g°C)
