Pressure
The amount of force exerted on a certain area
Pressure =
Force / Area
Gas Pressure
The force exerted by gas particles hitting the walls of the container
Force
Any push or pull exerted on an object
Area
The amount of surface space
Temperature
A measure of the average Kinetic Energy of the particles in a substance
Volume
Amount of space
High Temperature =
Faster particles
Low Temperature =
Slower particles
Faster particles =
Higher pressure
Slower particles =
Lower pressure
Smaller volume =
Higher pressure (more collisions)
More particles =
Higher pressure (more collisions)
Factors that affect gas pressure
(1) Amount of particles
(2) Temperature (particle speed)
(3) Volume (amount of space)
Fewer particles =
Lower pressure (fewer collisions)
More collisions =
Higher pressure (more contact with container walls)
Fewer collisions =
Lower pressure (less contact with container walls)
