# 10grm ice at 0 degree Celsius + 1grm steam at 100 degree Celsius. Find mass of left substitute. Sir please briefly explain this type of problems.

Asked by amitjena226 17th January 2018, 10:52 AM
let x gm of ice melt and the final temperature of mixture is 0°C.

Heat loss of steam from 100°C to 0°C water :-  ms×(Lv+100) , where ms is mass of steam in kg Lv is latent heat of vapourization.

Heat gain of x gm of ice = x ×10-3 × Lf, wher Lf is laten heat of fusion of ice

x × Lf = ms×(Lv+100)

Lf = 334 kJ/kg,  Lv = 2260 kJ/kg,

hence 6.77 gm of ice melts into water

total water content = 6.77gm from melting of ice+1gm of condensed steam = 7.77gm

left out ice = 3.23 gm
