a balloon is filled with .50 moles out of gas at room temp and normal room pressure, the balloon volume would be 11.2L. if you heat the balloon keeping the room pressure and amount of gas unchanging, what would be the effect on the volume of the balloon?

  • osu - ,

    The ideal gas law states that for n moles of gas, the following relation applies:

    PV=nRT
    where
    P=pressure
    V=volume
    R=constant
    T=temperature in °K

    In the present case,
    P and n (and R) remain constant, from which we can conclude that the volume varies directly proportional to the temperature of the gaz (in °K).

    Note: temp. in °K = temperature in °C+273.15
