Water Vapor Pressure
Water Vapor Pressure at high temperature and high pressure (steam) of course is well known in driving turbines to generate electricity or to drive compressors or pump etc.
In some distillation processes such as distilling heavy hydrocarbon water vapor plays a role in enhancing vaporization at lower temperature to prevent hydrocarbon thermal cracking.
Presence of water vapor in air control rate of human being and animal evaporation to maintain constant body temperature and skin cell content balance. It acts as a lubricant to smooth breathing and proper lung functioning.
It is essential for plantation to survive, and to life cycle Equilibrium.

How does temperature affect vapor pressure?
Vapor pressure increases with temperature. As the temperature increases ,molecules of liquid find it easier to escape.
What The study of pressure on liquids?
The study of liquids at rest called is known as hydrostatics. This a study of the mechanism of fluids which is a branch of physics.
What are the different kinds of volatile liquids?
Liquid that has a high boiling point. A liquid that releases molecules as a vapor.
What happens to the pressure inside a container when the temperature of a fluid is increased?
When heated, temperature increases. You may have already guessed that. Most substances, but not all, increase in volume as the temperature increases at constant pressure. The pressure would remain the same if the fluid was in an open container.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor

Can vapor pressure occur in open container?
Yes. In fact vapor pressure is an important factor in weather.
What are the different kinds of volatile liquids?
Liquid that has a high boiling point. A liquid that releases molecules as a vapor.

Edward George Meiter has written: 'A study of the relation between flash-point and vapor pressure of burning oil' -- subject(s): Flammable liquids, Vapor pressure
How does the vapor pressure of water at 10 degrees celsius with its vapor pressure at 50 degrees celsius?
Do you mean, how does the pressure of water vapor at 10˚C compare with its pressure at 50˚C?The vapor pressure of water is the pressure at which steam is saturated. Above this pressure, the water would begin to condense. In a gas mixture saturated with water vapor, the vapor pressure is equal to the partial pressure. The vapor pressure is a function of temperature. Many equations of state can predict vapor pressures of liquids but the best ones are also rather complex and require considerable expertise to use. For most purposes, there are several simpler empirical equations which can estimate the vapor pressures of liquids with sufficient accuracy for most purposes.One of the simplest is the Antoine equation which has the form:log10Pvap = A - B/(C+T) where the Pressure (P) is in mmHg and the Temperature (T) is in °C.For water in the range from 1 °C to 100 °C, the constants have the values:A = 8.07131B = 1730.63C = 233.426Using these values, the vapor pressure of water can be estimated as:Pvap(@10 °C) = 9.158817 mmHgPvap(@50 °C) = 92.29989 mmHg... so the vapor pressure of water at 50 °C is roughly 10 times the vapor pressure at 10 °C.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
Does Iodine have a high or low vapor pressure?
By agreement, the very definition of 'volatile liquid' identifies a liquid which evaporates at Standard Temp/Pressure. The rate at which it evaporates is called its vapor pressure. High VP means it will evaporate rapidly at STP. Theoretically, any material, element or compound, in liquid form can be made to evaporate by increasing the temperature and reducing the pressure. Gas-deposition makes use of this theory to build industrial diamonds from hot, highly-pressurized carbon vapor.
The vapor pressure of CO2 is lower than the vapor pressure of water?
No, the vapor pressure of CO2 would be higher. Think of it like this, if you compress the molecules in gas enough, they will be close enough together to form a liquid. Both CO2 and water can exist as liquids and gas. At atmospheric pressure (14.7psi) or normal everyday pressure, water is a liquid and CO2 is a gas. This means that 14.7psi is not enough pressure to compress CO2 into the liquid state. Therefore, CO2 has a higher vapor pressure because it requires more pressure to become a liquid. Looking at it from the other side, if you had extremely high pressure where CO2 and water were both liquids and you started lowering the pressure, CO2 would become a vapor first once you went below a certain high pressure, and water wouldn't become a gas until you went well below atmospheric pressure.
Which lquids evaporate at room temperature?
All liquids will evaporate to some extent at room temperature. The extent of evaporation depends on the vapor pressure of the liquid and the volume of distribution. However, for some liquids the vapor pressure is so low that evaporation is nearly negligible at room temperature.
