The pressure exerted by a gas is a function of the Options.

Example of pressure exerted by gas. The SI unit for Gas pressure. B speed of the gaseous molecules. The gas molecules move randomly along the given volume.

Gases Exerting Pressure We know that there are many gases like Nitrogen Oxygen Carbon Dioxide in the atmosphere When these gases come in contact with a substance there is collision of molecules of gas with molecules of substance This causes air pressure Example 1 - Inflating a balloon. Gas pressure is caused by the force exerted by gas molecules colliding with the surfaces of objects Figure 1. In this video we will derive the expression for pressure exerted by the gas on the walls of the container using the maxwell-Boltzmann velocity distribution.

Consequently the total pressure exerted by a mixture of gases is the sum of the partial pressures of the components Daltons law of partial pressures. Mean Kinetic energy per unit volume 23. The pressure exerted by a liquid is small just under the surface of the liquid.

These collisions of the gas particles with the walls of the container. Gases possess high kinetic energy and negligible force of attraction so they can move constantly moving with high speed in all directions. So V l³.

The pressure exerted by a liquid changes with depth in the liquid. Pressure per unit volume is two third of the mean kinetic energy. The SI unit for Gas pressure is expressed in Pascals Pa.

P total P 1P 2 P n P t o t a l P 1 P 2. We will find out this expression in different terms. Expression for Pressure Exerted by a Gas Using Kinetic Theory of Gases.
