When steam condenses to H2O(l)liquid water, heat of 2.26kJ is released per gram. The heat from 168 grams of steam is used to heat a room containing 6.44 X 10 power of 4 of air. The specific heat of air at normal pressure = 1.015J/g.C. What is the change in air temperature(, assuming the heat from the steam is all absorbed by air)
