(5.6) Temperature and Particle Motion

2. The average speed of gas particles depends only on the temperature and the mass of the particles.

3. Temperature Hotter particles tend to move FASTER.
Colder particles tend to move SLOWER

4. Mass Heavier particles tend to move SLOWER
Lighter particles tend to move FASTER

5. Kinetic Energy (KE) is the energy an object possesses because of its motion, KE = mv2/2 (m is mass and v is velocity). Temperature is the average kinetic energy of the particles in a sample of matter.

6. Comparing Fahrenheit, Celsius, and Kelvin Temperature Scales

8. Heat is the amount of energy transferred between two objects at different temperatures. Energy always flows from a warmer object to a cooler one.

9. Particles STOP all motion
