Kinetic Theory Why does temperature change the state of matter?
45
Kinetic Theory: all matter is made of particles that are always moving.
Temperature: - a measurement of Kinetic Energy (how fast particles are moving) Measured in degrees Celsius or in Kelvin (which we will get to later) Absolute zero – the temperature at which all movement of particles stops - This has never been reached
46
