# How to find the pressure of gas

In another lesson, you learned that the ideal gas law is expressed as PV = nRT. In this video lesson, we'll go one step further, examining how to. Ideal gas law equation calculator solving for pressure given moles, universal gas constant, temperature and volume. Most gases closely follow an equation of state called the ideal gas law, P=nRTV.

The pressure of a gas is the force that the gas exerts on the walls of its In order to calculate pressure through the barometer tool, one would. Treat each gas as an “ideal” gas. An ideal gas, in chemistry, is one that interacts with other gases without. The gas laws deal with how gases behave with respect to pressure, volume, . of gas contain the same number of moles, chemists could now determine the.

In day-to-day life, we measure gas pressure when we use a barometer to check the atmospheric pressure outside or a tire gauge to measure the pressure in a. However, taken all together, this large number of impacts of gas molecules exerts a considerable force onto the surface of the enclosure: the gas pressure (see. Gas Laws. Pressure or Volume. Constant Temperature; T. Original pressure x Original Volume=Final pressure x Final Volume. P1V1=P2V2 Isothermic. Pressure.
