How do you convert mm Hg humdity to relative humdity in percentage?
From Wikipedia, article "relative humidity": "It is defined as the ratio of the partial pressure of water vapor in the air-water mixture to the saturated vapor pressure of water at the prescribed temperature." So, you somehow measure the partial pressure of water vapor, look up the saturated vapor pressure of water for the current temperature, and take the ratio.
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
2.90
What are the factors affect air pressure?
Three factors that affect air pressure are temperature, altitude, and water vapor.
Are variables in evaporation?
For evaporation from a pure water surface, the rate of evaporation is proportional to the difference in vapor pressure between that of the water surface and that of the bulk air over it. The vapor pressure of water in turn depends on its temperature.
What is the boiling point of water in space?
The boiling point of a liquid is the temperature where the vapor pressure is equal to the atmospheric pressure. Vapor pressure increases with temperature, as you heat the water up the vapor pressure keeps increasing until it matches the atmospheric pressure, then it is boiling. Space isn't quite a perfect vacuum, so the boiling point wouldn't be 0, but it would be very very low.
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 is affected by surface water vapor and temperature?
air pressure

What is the density of water vapor?
The density of water vapor can vary depending on temperature and pressure. At standard temperature and pressure (STP), the density of water vapor is approximately 0.804 grams per liter (g/L). However, as temperature increases or pressure decreases, the density of water vapor decreases.
Why does plain water boil faster then salt water?
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.
Why does lowered air pressure allow water to boil at room temperature?
Less force pushes down on the liquid, making it easier for gas to escape
What is affected by surface elevation water vapor and temperature?
air pressure
What is the water vapor pressure at body temperature?
It is determined by Dalton's law.
What is the affected by surface elevation water vapor and temperature?
air pressure
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
How water turns into vapor at normal temp?
A large DECREASE in the surface pressure will result in water turning to water vapor at room temperature.
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.
