    Answer:

    Initial temperature of the gas cylinder was 167.7K

    Explanation:

    Based on Gay-Lussac’s law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:

    P1*T2 = P2*T1

    Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.

    Replacing:

    P1 = 1.25atm

    T2 = 354.2K

    P2 = 2.64atm

    T1 = ?

    1.25atm*354.2K = 2.64atm*T1

    167.7K = T1

    Initial temperature of the gas cylinder was 167.7K
