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