SUMMARY
The change in temperature of 1 kg of moist air when 1 g condenses can be calculated using the heat of vaporization and specific heat values. The heat of vaporization is 2.5 x 10^6 J/kg, and the specific heat at constant pressure is 1004 J/K.kg. The condensation process will increase the temperature of the moist air due to the release of latent heat. To find the temperature change, divide the heat of vaporization by the specific heat, ensuring to account for the mass of the air in the calculation.
