A hot air balloon is filled with hot air and the hot air forces the volume of the balloon to expand until the density of the gas in the balloon is less than the density of the outside air. The volume must be 20% larger than the balloon would be at STP in order for the balloon to float. If you double the temperature inside the balloon will it float?

  1. Of course.

    V=nRT/P

    density=mass/volume=mass*P/nRT
    if you double temp, density goes to 1/2.
