When a solute is added to a solvent, the vapor pressure of the solvent (above the resulting solution) is lower than the vapor pressure above the pure solvent.
if the solution is non volatile like water, you can add something like Table salt (NaCl) or Soap (sodium stearate) as a solute.
if the solution is volatile like xenon, you can add something like krypton as a solute.

Vapor pressure is measured when a liquid and its vapor are?
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure
The difference between vapor pressure of a pure solvent and its partial pressure?
vapor pressure of a pure solvent is the pressure needed for the gas to escape the pure solvent in vapor form. its partial pressure in this case will be the pressure of that escaped vapour (in the mixture of air). in simpler terms vapor pressure describes a single condensable system (just the vapor of the solvent and the liquid state of the solvent) while its partial pressure describes the multicomponent system (air). they are essentially the same thing describing different systems
Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Explain why vapor pressure increases as temperature increases?
Vapor pressure increases as temperatures increase because water will evaporate in hot weather. This evaporation rises increasing the vapor pressure. This is why many areas have high humidity in the summer.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
What is humidity and how is it affected by temperature and pressure?
Simply humidity is percentage of moisture in atmosphere or in a gas.When temp. increases pressure reduces, that means gas percentage reduces in unit volume. But due to latent heat of water vapor expansion of vapor is less which results in increase in humidity. And when temp reduces, gaseous volume increases result in less humidity. The above case is for constant water vapor in air. If rain is there humidity increases because of chance of getting to water vapor is more.
Why does plain water boil faster then salt water?
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
What will a hydrate do if its vapor pressure is higher than the vapor pressure of the water vapor in the air?
Lose Effloresce
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
What is crude oil true vapor pressure?
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F)
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.

The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
Is increase of vapor pressure a colligative property?
The lowering of the vapor pressure is a colligative property.
Which of the colligative properties is not dependent on vapor pressure boiling point elevation vapor pressure reduction osmotic pressure?
Osmotic pressure.
