Vapor pressure is a measure of a substance's tendency to evaporate. Higher vapor pressure leads to more rapid evaporation, which can create a lifting effect on the liquid. This lifting effect is evident with substances that have high vapor pressure, as they can form vapor bubbles that displace the liquid, causing it to rise.

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 is the vapour pressure of liquids?
Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
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 effect of nature of liquid on the rate of evaporation?
heat, humidity,wind and the surface area of container that it is in.
What is the vapour pressure of liquids?
Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.
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.
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
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.
What has an effect on air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
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 has an effect on earths air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
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 are 3 examples of gases dissolved in liquids?
liquid;vapour and ice
What effect do you think that has no air pressure on the ground?
Without atmospheric pressure, water will boil to vapour, so as our blood and body would explode. Pressure is what that keep water in liquid and solid state on earth.
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.
