Problem 2.208

Assuming the saturated water vapour to be ideal, find its pressure at the temperature 101.1∘C101.1^{\circ} \mathrm{C}.

Reveal Answer
psv≈p0(1+qMΔT/RT2)=1.04 atm where q is the specific heat of vaporization, p a is the standard atmospheric pressure,ΔT=1.1 Kp_{s v} \approx p_{0}\left(1+q M \Delta T / R T^{2}\right)=1.04 \text { atm where } q \text { is the specific heat of vaporization, p a is the standard atmospheric pressure,} \Delta T=1.1 \mathrm{~K}
