Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What is the unit of integrated water vapour?
kg/m3
Does vapour pressure depend upon the nature of a liquid?
because nature of liquid means a attractive forces less attractive forces means low vapour pressure
Ethylene glycol has a vapour pressure of 14.9mmHg at 373K and a vapour pressure of 49.1 mmHg at 398K calculate the enthalpy of vapourization of ethylene glycol?
59.0 KJ/mol
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Which one has high vapour pressure water or alcohol?
alcohol has high vapour pressure than water at room temperature.
Why the relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.

How do you calculate actual vapour pressure?
pressure=force/area

What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling

Is vapour pressure intensive property?
yes
What is the unit of integrated water vapour?
kg/m3
What is the ratio of RH?
Relative humidity (RH) is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
