What is the effect of nature of liquid on the rate of evaporation?
heat, humidity,wind and the surface area of container that it is in.
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 are the different kinds of volatile liquids?
Liquid that has a high boiling point. A liquid that releases molecules as a vapor.
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 true vapour pressure?
Pa, pascal
Why the vapour pressure of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
When does boiling point occur?
For water it is 100 degrees celsius, however it is different for other liquids ------------------------- Generally, boiling point is the temperature at which the liquid's vapour pressure is equal to the external atmospheric pressure.
What is the effect of nature of liquid on the rate of evaporation?
heat, humidity,wind and the surface area of container that it is in.
What factors affect the vapour pressure of a liquid?
Vapor pressure or equilibrium vapor pressure are the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed bottle. All liquids and solids have a tendency to evaporate into a gaseous form, and all gases have a tendency to condense back to their liquid or solid form.The equilibrium vapour pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile
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.
What are 3 examples of gases dissolved in liquids?
liquid;vapour and ice
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.

What is the boiling point of water vapor?
Water vapour doesn't boil, but liquid water's boiling point is 100 degrees C, or 212 degrees F.boiling point is that point at which the vapour pressure of a liquid become equal to the atmospheric pressure at a particular temperature.for exampleboiling point of water is 100 degree Celsiusthat isat this temperature vapour pressure of water is equal to the atmospheric pressureso there is no boiling point of water vapour since it is not a liquid and boiling point is only determined for liquids not gases or vapours .also vapour has 540 kilo calories of heat known as latent heat of vapourisation at 100 degree celsius.
