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

Charles' Law Graph

directly proportional

Boyle's Law Graph

inversely proportional

solid

The particles are tightly packed. Definite shape and definite volume.
The particles do not move around.

liquid

The particles are close together. Has a variable shape and definite volume.
The particles vibrate, move, and slide past each other.

gas

The particles are very separated. Variable shape, variable volume.
The particle vibrate and move quickly.

Liquid

can be poured and take on the shape of its container (variable shape). Has mass and definite volume.

gas

A state of matter that has a variable shape and variable volume. Has a high kinetic energy.

Matter

anything that takes up space and has mass

Particles

Tiny atoms that make up all matter

atoms

basic particle from which all elements are made

matter

anything that has mass and takes up space (has volume)

Temperature

A measure of the kinetic energy (speed) of particles

Kinetic Energy

The energy of motion. Higher temperature = more kinetic energy
