A cylinder of gas at 23 C is measured to have a pressure of 150,000 Pa.?

(a) What would its pressure be if its temperature were raised to 78 C with the volume of the container remaining constant?

(b) The cylinder of gas is then returned to 23 C and a pressure of 150,000 Pa. What would the temperature of the gas be if its pressure were raised to 220,000 Pa by heating it with the volume of the container remaining constant?

    (a)

    T1 = 23+273 = 296K

    T2 = 78+273 = 351K

    P1 = 150,000 Pa

    P1/T1 = P2/T2

    P2 = P1 x T2/T1

    Put the values in and solve for P2

    (b)

    T1 = 23+273 = 296K

    P1 = 150,000 Pa

    P2 = 220,000 Pa

    P1/T1 = P2/T2

    T2 = T1 x P2/P1

    Put the values in and solve for T2. RemeMber to subtract 273 if you want the temperature in degrees C rather than K.
