Gas molecules keep their distance from every other and are in continuous motion. They proceed to move in one direction until they come into contact with an object. Gas increases when put in a closed container. The molecules proceed to relocate about, filling the container. Lock strike the sides of the container, and also each hit creates pressure. Three factors influence the press of the close up door container.

You are watching: Three factors that affect gas pressure


Gas push in a closed container is the result of the gas molecules hitting the inside of the container. The molecule move around and space attempting come escape the container. As soon as they can not escape, they strike the inside wall and climate bounce around. The more molecules striking the inside wall of the container, the higher the pressure. This concept represents the kinetic theory of gases.


Changing the temperature affects push in a closeup of the door container. Advanced the temperature, and the press increases. This occurs because of the raised movement that the gas molecules. Twin the temperature, and also you dual the pressure. This describes why aerosol cans have actually warnings around exposure to heat. Litter an aerosol have the right to into a fire and it will certainly explode at the suggest when that walls deserve to no much longer withstand the boosted pressure of its contents. Two French scientists, Jacques Charles and also Joseph luigi Gay-Lussac, first demonstrated this principle; the regulation explaining it bears their names.


The volume the a gas and also its push are inversely related. To decrease the volume, and also the push increases. This relationship is dubbed Boyle"s legislation in respect of Robert Boyle who very first observed that raised pressure lower volume. As the volume a gas rectal decreases, the molecules of the gas are compelled closer together, but their movement continues. They have actually less street to travel to affect the container walls so castle strike much more often, for this reason creating an ext pressure. This variable is the basis for the car piston. That compacts the air-fuel mixture in the cylinder, thereby boosting pressure in ~ the cylinder.


Increase the variety of particles in a container, and also the push of the mechanism within the container increases. Much more molecules mean an ext hits against the container walls. Raising the number of particles method you have actually increased the thickness of the gas. This third factor is component of the right gas law, which describes how these three factors -- temperature, volume and also density -- interact with each other.
