To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln(P1/P2) = (ΔHvap/R)((1/T2) – (1/T1)).
Q. Why Vapour pressure does not depend on amount of liquid?
It does not depend on the amount of liquid as long as at least a tiny amount of liquid is present in equilibrium with the vapor. The equilibrium vapor pressure does, however, depend very strongly on the temperature and the intermolecular forces present, as shown for several substances in Figure 11.5.

Q. What is the vapor pressure of liquid?
The vapor pressure of a liquid is the point at which equilibrium pressure is reached, in a closed container, between molecules leaving the liquid and going into the gaseous phase and molecules leaving the gaseous phase and entering the liquid phase.
Q. How do you calculate vapor load?
So in order to calculate the Boilup volume, i’ll transform the equation as V = (n x R x T)/P. and some more transformation i’ll prefer V = ((W/M) x R x T)/P, So here right now everything is clear , based on the composition of batch volume you consider, you can generate the data for W, M.
Q. What is the approximate vapor pressure when the liquid water boils at about 50 C?
The correct answer is 230 mmHg. Hence, when liquid water boils at 50°C, the water vapor pressure is (760/2) mmHg or 230 mm Hg.
Q. What are the three process involved in the change of physical state of water?
Changes of state are physical changes. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.
Q. What are the different forms or states that water has and what is needed for water to change from one state to the other?
Water can exist either as a solid (ice), a liquid (water), or a gas (water vapor). Water on the on surface of Earth is constantly changing between these three states. Ice can change to become water or water vapor. Water can change to become ice or water vapor.
