1. Temperature Feeling hot, hot, hot….

2. Temperature Temperature – a measurement of how much kinetic energy the particles contain

3. Three scales used to measure Temperature:

4. Fahrenheit Scale The Fahrenheit Scale was the first invented but is no longer used in science because it goes against the metric system

5. Celsius Scale On the Celsius scale: Freezing point of pure water is 0 o C Boiling point of pure water is 100 o C

6. Kelvin Scale This is the SI scale used to measure temperature “O” is not used with Kelvins This scale’s lowest temperature is ZERO.

7. Converting from Celsius to Kelvin… K = o C + 273

8. Absolute Zero Absolute zero is the lowest possible temperature. It is the temperature at which all motion of particles stop. Absolute Temp Video

9. Will it ever be possible to STOP all motion of a particle?
