You are watching: What are the three factors that affect gas pressure
Gas push in a close up door container is the result of the gas molecule hitting the inside of the container. The molecules move about and space attempting come escape the container. Once they can not escape, they strike the inside wall surface and climate bounce around. The more molecules to mark the inside wall surface of the container, the higher the pressure. This ide represents the kinetic theory of gases.
Changing the temperature affects pressure in a close up door container. Progressive the temperature, and the pressure increases. This occurs as result of the increased movement the the gas molecules. Dual the temperature, and also you dual the pressure. This defines why aerosol cans have actually warnings about exposure to heat. Throw an aerosol deserve to into a fire and it will explode at the suggest when the walls deserve to no longer withstand the enhanced pressure the its contents. 2 French scientists, Jacques Charles and Joseph luigi Gay-Lussac, very first demonstrated this principle; the law explaining it bears their names.
The volume of a gas and also its press are inversely related. Diminish the volume, and the pressure increases. This connection is dubbed Boyle\"s legislation in respect of Robert Boyle who an initial observed that boosted pressure lower volume. As the volume a gas rectal decreases, the molecules of the gas are forced closer together, but their movement continues. They have less street to take trip to impact the container wall surfaces so they strike more often, thus creating an ext pressure. This variable is the basis for the car piston. The compacts the air-fuel mixture in the cylinder, thereby increasing pressure in ~ the cylinder.
Increase the variety of particles in a container, and also the press of the mechanism within the container increases. Much more molecules mean more hits against the container walls. Raising the number of particles way you have increased the thickness of the gas. This 3rd factor is component of the ideal gas law, which describes how this three components -- temperature, volume and density -- connect with each other.
