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.
In an open system the vapor pressure is equal to?
In an open system, the vapor pressure is equal to the partial pressure of the vapor above the liquid at a given temperature. Unlike in a closed system, where vapor pressure can reach a dynamic equilibrium with the liquid phase, in an open system, vapor can escape, preventing the establishment of equilibrium. Therefore, the vapor pressure is not fixed and can vary depending on conditions such as temperature and the amount of vapor present.
What is sub cooled vapor?
Subcooled vapor refers to a vapor that is at a temperature lower than its saturation temperature at a given pressure. In other words, it is a vapor that is in a superheated state but exists at a temperature below its boiling point at the current pressure. Subcooled vapor is not in equilibrium with its liquid state and is considered to be in a superheated state.
What is the percentage of water vapor a certain volume of air contains relative to the maximum amount?
The percentage of water vapor in a certain volume of air relative to the maximum amount it can hold is referred to as the relative humidity. It is calculated by taking the actual amount of water vapor present in the air, dividing it by the maximum amount the air can hold at that temperature, and then multiplying by 100. For instance, if the air contains 10 grams of water vapor, and the maximum capacity at that temperature is 20 grams, the relative humidity would be 50%.
What occurs when heat energy is removed from a liquid-vapor system in equilibrium?
When heat energy is removed from a liquid-vapor system in equilibrium, the temperature of the system decreases, leading to a shift in the equilibrium position. According to Le Chatelier's principle, the system will respond by favoring the exothermic process, which in this case is the condensation of vapor into liquid. As a result, more vapor will condense, increasing the amount of liquid while decreasing the vapor phase until a new equilibrium is established.

What is the temperature at which the rate of evaporation equals the rate of condensation?
The temperature at which the rate of evaporation equals the rate of condensation is known as the equilibrium vapor pressure. At this temperature, the vapor pressure of a liquid is equal to the external pressure, leading to a dynamic equilibrium between the liquid and vapor phases.
What is the approximate vapor pressure when the gas condenses at 80oC?
The vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. The vapor pressure depends on the temperature and the substance.
What kind of liquid pressure is exerted at equilibrium and is dependent on temperature only?

Therefore, the vapor pressure is not fixed and can vary depending on conditions such as temperature and the amount of vapor present.
Vapor pressure is measured when a liquid and its vapor are?
in a state of dynamic equilibrium at a constant temperature. At this point, the rate of vaporization equals the rate of condensation, resulting in a constant pressure above the liquid known as the vapor pressure.
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.
What is sub cooled vapor?
Subcooled vapor refers to a vapor that is at a temperature lower than its saturation temperature at a given pressure. In other words, it is a vapor that is in a superheated state but exists at a temperature below its boiling point at the current pressure. Subcooled vapor is not in equilibrium with its liquid state and is considered to be in a superheated 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 difference between vapor pressure and vapor density?
Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase (liquid or solid) at a given temperature. Vapor density, on the other hand, is the mass of a vapor per unit volume of air. In essence, vapor pressure relates to the equilibrium between the vapor and its condensed phase, while vapor density pertains to the mass of vapor in a given volume of air.
