How does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
The vapor pressure of water at 50ºC will be greater than that at 10ºC because of the added energy and thus greater movement of the water molecules. If one knows the ∆Hvap at a given temperature, one can calculate the vapor pressure at another temperature. This uses the Clausius-Clapeyron (sp?) equation. It turns out the vapor pressure of water at 10º is 9.2 mm Hg, and that at 50º is 92.5 mm Hg.
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.
How does altitude change the boiling point of water?
Water boils when its vapor pressure equals the vapor pressure of the surrounding atmosphere. The atmosphere surrounding the water exerts a pressure, preventing gas molecules escaping from the surface. At higher altitudes, this pressure is much lower so water will boil at a lower temperature.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
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 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.
What variables can change air pressure?
Temperature, volume, height , and water vapor are variables that change air pressure.
How many grams of sucrose must be added to 500 g of water at 100 celsius to change the vapor pressure to 755 mm Hg?
101 g

How does air pressure change as water vapor pressure increases?
As water vapor increases, pressure decreases due to the fact that water is made up of hydrogen and oxygen, which is lighter than what most of the air is made out of, oxygen and nitrogen.
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.
