Question

given that the specific heat capacities of ice and steam are 2.06 J/g °C and 2.03 J/g °C. Calculate the total quantity of heat evolved when 10.0 g of steam at 200 °C is condensed , cooled, and frozen to ice at -50°C

Answer 1

molar heat of vaporization is 40.6 Kj/mol and molar heat of fusion is 6.02 KJ/mole. And the heat capacity is 4.18 J/ g°C
