Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.

Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will 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.
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.
What statements is true about vapor pressure?
The vapor pressure of 1 m sucrose (C12H22O11) is higher than the vapor pressure of 1 m NaCl where the solvent is water Sea water has a lower vapor pressure than distilled water. The vapor pressure of 0.5 m NaNO3 is the same as the vapor pressure of 0.5 m KBr, assuming that the solvent in each case is water The vapor pressure of 0.10 m KCl is the same as the vapor pressure of 0.05 m AlCl3 assuming the solvent in each case is water The vapor pressure of 1 m NaCl is lower than the vapor pressure of 0.5 m KNO3, assuming that the solvent in each case is water The vapor pressure of 0.10 m NaCl is lower than the vapor pressure of 0.05 m MgCl2 assuming the solvent in each case is water.
Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
What is the vapor pressure a liquid at its normal boiling temperature?
Vapor pressure of a liquid at its normal boiling temperature is simply the atmospheric pressure, aka 1 atm, 760 torr, etc. This is by definition.
Define vapor pressure thermometer?
A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
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 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
What is the definition of convergence pressure?
In chemistry, the convergence pressure is a specific point where two component systems converge. These two systems usually have different liquid vapor equilibriums.
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)
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
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
