Gas pressure can be measured using several different instruments including:
Hydrostatic gauges - like a manometer or barometer
Piston gauges - like tire pressure gauges
Mechanical gauges - which use deflection of diaphragm, a capsule, or a set of bellows, which will change shape in response to the pressure of the region in question
Bourdon tube - a type of mechanical gauge that uses a coiled tube (Bourdon tube) that deflects with pressure
Electronic - including:
Piezo resistive Strain Gage
Capacitive
Magnetic
Piezoelectric
Optical
Potentiometric
Resonant
Thermal conductivity (conductivity of gasses changes with density - has to be calibrated to the gas)
Ionization (best for low pressure gases - has to be calibrated to the gas)

When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
Can vapor sublimate?
No, a vapor is a gas. Sublimation is the process by which a solid becomes a gas (vapor).
What instrument measures water vapor?
dewpoint apparatus
Distillation is a process that can separate two liquids using what?
Distillation separates two liquids that have significantly different vapor pressures. The usual process uses heat to evaporate the gas with the higher vapor pressure. The gaseous form of the liquid is moved to a different container, where it is cooled, causing the gas to condense back into a liquid. In practical application, there is a limit to how completely two substances can be separated using distillation, because some of the substance with a lower vapor pressure will always evaporate along with the substance with higher vapor pressure.
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.
How does pressure help in liquefaction of a gas?
Once pressure reaches vapor pressure, gas will liquify at that temperature.
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
What does a pressure sensor do?
It measures the pressure of a fluid or gas.
Vapor pressure results from?
pressure of gas over its liquid equilibrium
What is boiling in matter?
Phase shift from liquid to gas (vapor), where the vapor pressure is just equal to the atmospheric pressure.
What is the gas pressure above a liquid at equilibrium called?
Vapor pressure
What is the approximate vapor pressure when the gas condenses at 80oC?
200
How does vapor pressure change with solubility?
solubility of a gas or solid?
The ideal gas law measures pressure in?
atmospheres A+
What is the measure of the force exerted by a gas above a liquid?
vapor pressure
Compare the vapor pressure of water at 10 C with its vapor pressure at 50 C?
Vapor pressure of water at 10 0C is less than that at 50 0C because, like gas pressure, as temperature rises, the kinetic energy of particles increases, thus increasing pressure. So the pressure of water vapor at 50 0C has more vapor pressure than at 10 0C.
