    Whenever you are doing calculations with gases and temperature, you must convert the temperature from C into Kelvin. Then, just plug in your values and do the calculation. So, for the first one,

    32C + 273 = 305 K

    63C + 273 = 336 K

    Then, P1/T1 = P2/T2

    575 torr / 305 K = P2 / 336 K

    P2 = 633 torr

    For the second one:

    P1/T1 = P2/T2

    575/305 = 5750 / T2

    T2 = 3050 K
