Find the pressure of saturated vapour as a function of temperature p(T) if at a temperature To its pressure is equals po. You may assume that the specific heat of vaporisation per unit of mass, q, is independent of temperature, that the specific volume of liquid is negligible compared to that of vapour, and that saturated vapour obeys the equation of state for an ideal gas. A small amount of water and saturated water vapour are in equilibrium in the closed vessel at a temperature T = 100°C. You can assume that the vapour is an ideal gas and the volume of water is negligible compared to that of vapour. The heat of vaporization of water is 2.26 × 10³ kJ kg-¹ If the temperature of the vessel goes up by AT = 0.5° C, determine the relative increase (in percent) of the mass of the saturated vapour in the vessel.

Find the pressure of saturated vapour as a function of temperature p(T) if at a temperature
To its pressure is equals po.
You may assume that the specific heat of vaporisation per unit of mass, q, is independent of
temperature, that the specific volume of liquid is negligible compared to that of vapour, and
that saturated vapour obeys the equation of state for an ideal gas.
A small amount of water and saturated water vapour are in equilibrium in the closed vessel
at a temperature T = 100°C. You can assume that the vapour is an ideal gas and the volume
of water is negligible compared to that of vapour. The heat of vaporization of water is
2.26 × 10³ kJ kg-¹
If the temperature of the vessel goes up by AT = 0.5° C, determine the relative increase (in
percent) of the mass of the saturated vapour in the vessel.
