When steam condenses to liquid water, 2.26 kJ of heat is released per gram. The heat from 168 g of steam is used to heat a room containing 6.44*104 g of air (20ft*12ft*8ft). The specific heat of the at normal pressure is 1.015 J/(g°C). What is the change in air temperature, assuming the heat from the steam is all absorbed by the air?
