    1. The problem statement, all variables and given/known data
    Suppose that 500g of water vapor condense to make a cloud about the size of an average room. If we assume that the latent heat of condensation is 600cal/g, how much heat would be released to the air?

    If the total mass of air before condensation is 100kg, how much warmer would the air be after condensation? Assume that the air is not undergoing any pressure changes, and use the specific heat of dry air at sea level 0.24 cal/(g x oC).

    2. Relevant equations
    I don't really know the formula to calculate

    3. The attempt at a solution
    I times 500*600=300,000

    That looks alright. 300,000 calories.

    0.24 cal of energy heats 1 g of gas by 1 deg. How much will 300,000 cal heat 100 kg of gas?

    I don't get your question.

    Do you know what heat balance is?
