What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Maximum pressure of vapor that builds up in a closed container?
The pressure produced by a vapor (gas) is a result of the collisions of the gas molecules with the sides of the container.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
When is water in equilibrium with water vapor?
When the concentration of the liquid (water) and gas (vapor) phases do not change.

What occurs at the molecular level when a solid-vapor equilibrium exists?
The rate of molecules overcoming attractive forces is equal to the rate of molecules entering the solid state.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
What is the difference between vapors and gas?
Strictly speaking, the terms "gas" and "vapor" are synonymous. The term "vapor" is often used to refer to the gaseous phase of something that may also exist as a liquid in equilibrium with the vapor or at a condition not too far removed from the observed condition of the vapor. In this context one might differentiate between a "vapor" and a "gas" by saying that a vapor is a saturated gas. Vapor is also sometimes used to refer to liquid droplets or particulates small enough to remain suspended in the air such as a mist, cloud, or fumes.

When is water in equilibrium with water vapor?
When the concentration of the liquid (water) and gas (vapor) phases do not change.
Is liquid water a water vapor?
No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.
What is the relationship between the rate of evaporation and the rate of condensation of the vapor of a liquid in a closed container and has a constant vapor pressure?
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor. -KarkatHorns
Does covering water slow down evaporation?
The answer to this problem is not as simple as it seems. When water evaporates, an equilibrium exists between the water vapor and liquid water. Normally, the water vapor is disbursed into the surrounding air, causing the equilibrium to shift in the direction of the water vapor product. By covering the water, the equilibrium is not shifted in this direction. Although the molecules are not evaporating more slowly, more of them reenter the water. Thus, the loss of liquid water slows (or stops if the container is air tight), but the process of evaporation continues at the same speed; its just that the water vapor formed now reenters the solution as just as quickly as it forms.

What is the gas pressure above a liquid at equilibrium called?
