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.

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 is the vapour pressure of liquids?
Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.
What is the effect of vapour pressure on lifting of liquids?
Vapor pressure is a measure of a substance's tendency to evaporate. Higher vapor pressure leads to more rapid evaporation, which can create a lifting effect on the liquid. This lifting effect is evident with substances that have high vapor pressure, as they can form vapor bubbles that displace the liquid, causing it to rise.
What are the different kinds of volatile liquids?
Liquid that has a high boiling point. A liquid that releases molecules as a vapor.
Increasing hydrogen bonding has what effect on vapor pressure of water?
Increasing hydrogen bonding in water leads to a decrease in vapor pressure. Stronger hydrogen bonds require more energy to break, making it harder for water molecules to escape into the vapor phase. As a result, fewer molecules enter the vapor phase at a given temperature, resulting in lower vapor pressure. This is why water has a relatively low vapor pressure compared to other liquids.
Sublimation can occur because solids like liquids have?
Vapor pressure
What is the effect of the nature of the liquids on the rate of evaporation?
The rate of evaporation is influenced by the nature of the liquid through factors such as intermolecular forces, surface tension, and vapor pressure. Liquids with weaker intermolecular forces and higher vapor pressure tend to evaporate faster compared to liquids with stronger intermolecular forces and lower vapor pressure. Additionally, liquids with lower surface tension may also evaporate more rapidly.

Why does an equimolar mixture of acetone and chloroform have a lower vapor pressure than either of the pure liquids?
An equimolar mixture of acetone and chloroform has a lower vapor pressure than either of the pure liquids because of the phenomenon of Raoult's Law. According to Raoult's Law, the vapor pressure of a mixture of ideal liquids is lower than that of either pure liquid component due to intermolecular interactions between the different molecules. In this case, the molecules of acetone and chloroform interact and restrict the vaporization of each other, resulting in a reduced vapor pressure compared to the pure liquids.

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.
Can vapor pressure occur in open container?
Yes, vapor pressure can occur in an open container. Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase in a closed system. In an open container, vapor can still form above a liquid or solid substance, but it will not reach equilibrium as it can escape into the surrounding environment.
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.
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.
