1. Temperature 14.1

2. Temperature Temperature- a measure of a substances average kinetic energy. 1. hot particles will have more kinetic energy than cool particles. Thermometer- a tool that measures and indicates temperature. 1. Liquids such as mercury or alcohol expand when exposed to heat.

3. Temperature Scales Fahrenheit 1. Used mostly in the U.S 2. Boiling- 212 3. Freezing- 32 Celsius 1. Used everywhere but the U.S. 2. Boiling- 100 3. Freezing- 0 4. One degree Celsius= 1.8 degrees Fahrenheit.

4. Conversion Formulas Fahrenheit Temperature- (1.8 X Celsius) + 32 1. Practice Problems: a. 10 Celsius b. 3 Celsius c. 25 Celsius

5. Conversion Formulas Celsius Temperature= Fahrenheit – 32 1.8 1. Practice Problems: a. 45 Fahrenheit b. 12 Fahrenheit c. 85 Farhenheit

6. Kelvin Scale Based on absolute zero: a. Lowest possible temp (-273.15 C) b. Kinetic energy would be zero. Kelvin Temp= Celsius + 273 1. Practice Problems: a. 89 Celsius b. 32 Celsius

7. Heat The feeling of temperature is because of energy transfer. 1. Ex. Energy form your hand may cause ice particles to move faster and melt. Heat- energy transferred between objects of different temperatures.
