A Mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.

What types of equipment would be used to measure the boiling point of a liquid?
You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
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
What is the vapor pressure a liquid at its normal boiling temperature?
Vapor pressure of a liquid at its normal boiling temperature is simply the atmospheric pressure, aka 1 atm, 760 torr, etc. This is by definition.
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.
When the vapor pressure of a liquid is equal to the atmospheric pressure the liquid .?
it begins to boil - Monsy
What is the measure of the force exerted by a gas above a liquid?
vapor pressure
What types of equipment would be used to measure the boiling point of a liquid?
You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
Is used to measure the amount of the water vapor in the atmosphere?
barometer/hygrometer/thermometer
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.
Vapor pressure is measured when a liquid and its vapor are?
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure
Vapor pressure increases over a liquid in a closed container until?
Vapor pressure increases over a liquid in a closed container until the amount of vapor molecules rejoining the liquid equals the number leaving the liquid to form vapor. This is the characteristic vapor pressure of the substance.
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.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
