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
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.
Is it necessary to subtract the water vapor pressure of water in the butane experiment?
Yes, it is necessary to subtract the water vapor pressure of water when conducting an experiment with butane to account for the partial pressure of water vapor in the system. This helps ensure that the pressure measurement reflects the pressure of the butane gas alone.
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.
How does the addition of salt affect the boiling point of water?
Adding salt to water increases the boiling point of the water. This is because the salt disrupts the normal boiling process by reducing the vapor pressure of the water, requiring a higher temperature to boil.
How do you find the vapor pressure of water if the know temp of the water is 21 degrees C and the atmospheric pressure is 99.70 k Pa?
You can use a vapor pressure table or the Antoine equation to find the vapor pressure of water at 21 degrees C. The atmospheric pressure should not affect the calculation of the vapor pressure of water, as they are independent of each other in this context.
How does vapor affect air pressure?
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.

What has a higher vapor pressure water at sea level or the mountains?
water at sea level has higher vapor pressure
What effect does pressure have on water?
Water is effectively an incompressible substance, so pressure does not affect its' volume. However, its boiling and freezing points are directly related to the external pressure. Water boils when its vapor pressure is equal to the external pressure (or the atmospheric pressure if it is contained in some uncovered pot). Greater external pressure requires higher temperature for water so as to have that value of vapor pressure for it to boil. This is how pressure affects water.
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.
What are some elements that change air pressure?
temperature (heat), volume, water vapor, and altitude (how high or low it is) all affect air pressure
