    Question of ideal gas law and reaction spontaneity

    A 73.8 g sample of O2 gas at 0.0 oC and 5.065x10^4 Pa is compressed and heated until the volume is 3.26 L and the temperature is 27 oC. What is the final pressure in Pa?

    i converted the T to 273K and 300K do i convert the volume as well?

    Which set of values indicates a spontaneous change at all temperatures?
    ΔH > 0; ΔS > 0, ΔH < 0; ΔS < 0, ΔH > 0; ΔS < 0, ΔH < 0; ΔS > 0, or none

    Which set of values indicates a spontaneous change at low temperatures, but not at high temperatures?
    ΔH > 0; ΔS > 0,ΔH < 0; ΔS < 0, ΔH < 0; ΔS > 0, ΔH > 0; ΔS < 0, none

    Which set of values indicates a spontaneous change at high temperatures, but not at low temperatures?
    ΔH < 0; ΔS > 0, ΔH > 0; ΔS > 0, ΔH < 0; ΔS < 0, ΔH > 0; ΔS < 0 or none


    thanks
