    The volume of a hot air balloon is 150m*3 and the pressure is the same as the pressure of the atmosphere surrounding it,that is, 1.00 atm. What is the temperature of the air in the balloon if its STP volume is 120 m*3?

    P1*V1/T1 = P2*V2/T2

    You have 5 things and you need to find the 6th.

    Might have to do some conversions.

    Pressure = atmospheres

    Volume = liters

    Temperature = Kelvin ( 298.15 K is standard )
