1. Kinetic Theory Contents: Concept 0 Temperature Thermal Expansion (Qualitative)

2. Kinetic Theory 101 TOC The higher the temperature, the faster the molecules Temperature is proportional to average kinetic energy Average( 1 / 2 mv 2 ) = 3 / 2 kT - (not in data packet) )))((( (( )) ( ) (( )) ( ) )( ( ) Hot = more E k Cold = less E k Demo - show molecular motion device

3. Temperature TOC Water Boil Freeze Celsius 100 o C 0 o C Fahren. 212 o F 32 o F 0 o F Kelvins 373.15 K 273.15 K 0 K Not degrees K What 0 o F and 0 K mean Formulas for conversion Celsius: 30,20,10,0

5. Temperature 11 | 2 | 323 TOC

6. Kelvins = 273.15 + 37 = 310.15 K = 310. K :-) 310. K W What is 37 o C in Kelvins?

7. 273.15 K = 0 o C So it would be 77.35 - 273.15 = -195.80 o C (Boiling point of Liquid N 2 ) -195.80 o C W What is 77.35 K in o C

8. Kelvins = 273.15 + 128 = 401.15 K = 401 K :-) 401 K W What is 128 o C in Kelvins?

9. it’s 6 o F above freezing 6*5/9 = 3.3 o C 3.3 o C W What is 38 o F in o C
