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 formula to measure relative humidity?
HR= actual vapor pressure/ saturation vapor pressure
Compare the vapor pressure of water at 10 C with its vapor pressure at 50 C?
Vapor pressure of water at 10 0C is less than that at 50 0C because, like gas pressure, as temperature rises, the kinetic energy of particles increases, thus increasing pressure. So the pressure of water vapor at 50 0C has more vapor pressure than at 10 0C.
What is the vapor pressure of KCl?
Potassium chloride is a solid; the vapor pressure of solids is generally near zero.
What does barometric pressure have to do with evaporation?
Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.
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)
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
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.
What is the Reid vapour pressure of gasoline?
Reid vapor pressure (RVP) of gasoline is the vapor pressure at 100°F.
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.
