3.2 Pressure & Gas Laws

Home

Pressure

created by the force of particles colliding with the walls of a container or object

What will raising the temperature of a gas do?

increase the speed of particles, leading to more collisions and more pressure

What will reducing the volume of a gas do (making the container smaller)?

it will pack the particles together, creating more collisions and more pressure

What will increasing the number of particles do?

it will cause there to be more particles crammed in the same space, which will increase collisions, which will increase the pressure

Absolute Zero

a temperature of 0 Kelvin- when atoms completely stop moving

Charles's Law

states that the volume of a gas is directly proportional to its temperature in Kelvins (temperature increases, volume increases) Charles Takes Vacations

Boyles's Law

states that the volume of a gas is inversely proportional to its pressure (pressure increases, volume decreases). Boyle Plays Violin
