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?
The vapor pressure of water at 10°C is lower than its vapor pressure at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase.
What has a higher vapor pressure water at sea level or the mountains?
water at sea level has higher vapor pressure
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.
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 saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
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?
To change the vapor pressure of water to 755 mm Hg at 100°C, you would need to add sucrose to create a solution with a lower vapor pressure than pure water. The amount of sucrose needed to achieve this specific vapor pressure depends on the molal concentration of the sucrose solution and its van't Hoff factor. To calculate this accurately, you would need additional information about the sucrose-water system.
What happens to Vapor pressure when salt is added to water?
When salt is added to water, the vapor pressure of the solution decreases compared to that of pure water. This occurs because the dissolved salt ions disrupt the formation of water molecules at the surface, reducing the number of molecules that can escape into the vapor phase. This phenomenon is known as colligative properties, where the addition of a solute lowers the vapor pressure, resulting in a decrease in the solvent's tendency to evaporate.
How does air pressure change as water vapor pressure increases?
As water vapor pressure increases, the total air pressure also increases due to the addition of water vapor molecules to the air mixture. The increase in water vapor pressure results in a corresponding decrease in the partial pressure of the other gases in the air, such as oxygen and nitrogen. This change in air pressure can affect weather patterns and atmospheric conditions.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
The vapor pressure of water at 10°C is lower than its vapor pressure at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase.
What has a higher vapor pressure water at sea level or the mountains?
water at sea level has higher vapor pressure
When the vapor pressure of water is 70kpa the temperature of water is?
When the vapor pressure of water is 70 kPa, the corresponding temperature is approximately 45.6°C (114.1°F). This relationship can be determined using the water vapor pressure-temperature tables or the Antoine equation, which relates vapor pressure to temperature. At this pressure, water is in a state where it can coexist as both liquid and vapor.

What is vapor pressure of water?
The vapor pressure of pure water at 25 degrees Celsius is 23.8 torr.
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 is the vapor pressure of water at 21.5C?
The vapor pressure of water at 21.5°C is approximately 19.8 mmHg. This value represents the pressure exerted by water vapor when in equilibrium with liquid water at that temperature.
