If you have 8.3 liters of air in a balloon at room temperature (26°C) and heat the balloon to 38°C, what would the new volume be?

  • chemistry -

    V1/T1 = V2/T2
    T1 and T2 must be in Kelvin.

  • chemistry -

    i got 8.3/299.15 = v2/311.15

    but how do i get v2?

  • chemistry -

    If you put this on a piece of paper, more or less like this, then cross multiply. (Ignore the .....those are just there for spacing since we can't space on the boards.)

    8.3.......V2
    ------- = ----
    299.15.....311.15

    Cross multiply and you have
    299.15 x V2 = 8.3 x 311.15
    Then solve for V2.
