If a 250.0 mL sealed plastic bag starts out at a temperature of 19.0 °C and after sitting in the sun reaches a temperature of 60.0 °C, what will the new volume of the bag be? Assume the pressure inside the bag remains constant.

  • science -

    PV = kT
    if P remains constant, then

    V = kT (with a new k, of course)

    so, the V2 = (T2/T1)*V1

    recall that T is in °K, not °C
