    The new pressure at constant volume is 1066.56 kPa

    Explanation:

    Assuming constant volume, the pressure is diectly proportional to the temperature of a gas.

    Mathematically, P1/T1 = P2 / T2

    P1 = 880 kPA = 880 * 10^3 Pa

    T1 = 250 K

    T2 = 303 K

    P2 = ?

    Substituting for P2

    P2 = P1 T2 / T1

    P2 = 880 kPa * 303 / 250

    P2 = 266,640 kPa / 250

    P2 = 1066.56 kPa.

    The new pressure of the gas is 1066.56 kPa
