    Answer:

    34752.6 Pa.

    Explanation:

    Applying,

    P/T = P’/T’…………… Equation 1

    Where P = Initial Pressure, T = Initial Temperature, P’ =  Final pressure, T’ = Final temperature.

    make P’ the subject of the equation

    P’ = (PT’/T)………….. Equation 2

    From the question,

    Given: P = 33.7 kPa = 33700 Pa, T = 98.4°C = (273+98.4) = 371.4 K, T’ = (110+273) = 383 K

    Substitute these values into equation 2

    P’ = (33700×383)/371.4

    P’ = 34752.6 Pa.
