# Gas Pressure Formula

## Gas Pressure Formula

Gas Pressure Formula is defined as the force exerted by one substance on another per unit area. The force that the gas exerts on the container boundaries is defined as gas pressure. Gas molecules move at random across the given volume. They collide with the surface as well as each other during this movement. Each individual gas molecule’s impact is too small and difficult to visualize. However, the combined impact of all gas molecules constitutes the Gas Pressure Formula. The greater the number of collisions, the greater the pressure.

What is Gas Pressure Formula?

The ideal Gas Pressure Formula  equation is given by the ideal gas law as PV=nRT.

It can also be written as P=nRTV.

Where p denotes pressure, n denotes the number of moles of gas, R denotes the universal gas constant, and T denotes temperature. Gas pressure Formula is an important subtopic of the concepts explained in Thermodynamics and Thermochemistry.

Thermodynamics: Thermodynamics uses the terms thermo and dynamics to describe the rate at which heat flows. Thermodynamics was developed to improve the efficiency of heat engines by converting all of the energy into work and producing less heat as the product in the engine due to energy waste and engine wear and tear. The transformation of one energy into another is defined as thermodynamics.

Thermochemistry: In thermochemistry, thermos means heat and chemistry means chemical reaction, implying that the heat causes the chemical reaction to occur. In the year 1780, the French chemists Antoine Laurent Lavoisier and Pierre Simon de Laplace invented this new field of chemistry. They study the reactions that occur around them because the majority of the reactions occur due to heat absorption or heat release during the reaction or as the end product.

Thermochemistry is the branch of chemistry that describes the changes that occur in chemical reactions as a result of the presence of heat.
