    We use the formula:

    ΔP = (ΔH / ΔV) ln (T2 / T1)

    where,

    ΔH = change in enthalpy from solid to liquid = 4810 J/mol

    ΔV = change in volume from solid to liquid = 0.55 cm^3/mol

    T2 = 620 K, T1 = 600 K

    So,

    ΔP = (4810 / 0.55) ln (620 / 600)

    ΔP = 286.76 J/cm^3

    or converting to atm:

    ΔP = 2830 atm
