    Answer:

    466.65 K

    Explanation:

    Using the formula of  Pressure law,

    P/T = P’/T’……………….. Equation 1

    Where P = Intial pressure of gas, T = Initial temperature of gas, P’ = Final pressure of gas, T’ = Final temperature of gas.

    make T’ The subeject of equation 1

    T’ = (P’T)/P………………. Equation 2

    From the question,

    Given: P = 500 Torr = (500×133.322) N/m² = 66661 N/m², T = 35°C = (35+273) = 308 K, P’ = 101000 N/m²( Standard pressure)

    Substitute these values into equation 2

    T’ = (101000×308)/66661

    T’ = 466.65 K
