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.
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.
Is vapour pressure intensive property?
yes
Why must the lid be sealed when lavender flowers are heated in a container?
To stop water vapour escaping
Vapor pressure results from?
pressure of gas over its liquid equilibrium
Why does dew form on a cold soft drink can?
Condensation forms on any cold container because heat is transferred from water vapour in the air near the container to it, which warms the container and cools the vapour. The vapour turns back to liquid and condenses on the container surface.
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.............

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
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 is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
Does a vapour keep its shape?
No. It expands to fill any container it's in. If you pump it out of one container and into a different one, it changes its shape to match the new container.
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.
Is vapour pressure intensive property?
yes
