    Answer: 888.45 K or 615.3 °c

    Explanation:

    According to Gay Lussacs law which states that at constant volume, pressure of an ideal gas is directly proportional to it's absolute temperature.

    P/T = Constant

    Therefore, P1/T1 = P2/T2

    P1 = 6.7 atm

    T1 = 23°c = 273.15 + 23 = 296.15K

    Since P2 is tripled, then,

    P2 = 6.7 x 3 = 20.1 atm

    T2 = (20.1 x 296.15) : 6.7

    T2 = 888.45 K

    Or in celcius 615.3°c
