### Chapter 4.4(charles' law)

1. 1. CHARLE’S LAW
2. 2. What will happento the volume ofthe trapped airinside thiscontainer??- increases- decreases-same????
3. 3. Relationship Between V and T When the temperature increases because of sun:  The molecules move faster  The average kinetic energy also increases Therefore, the molecules will push the cylinder upward.
4. 4. Charles’ Law Charles’ Law state for constant mass and pressure:  “Volume directly proportional to its absolute temperature”
5. 5. Charles’ Law In mathematical equation:  V = constant T V1 = V2  So we can conclude: T1 T2 Must use in Kelvin
6. 6. Experiment of heated
7. 7. Volume against Temperature (⁰C) Volume O -273⁰C 100⁰C ɵ/⁰C
8. 8. Volume against Temperature (K) Volume Now we get!! V directly proportional to Absolute Temperature O ɵ/K
9. 9. Absolute Zero Temperature Absolute Zero temperature can be define as The lowest possible temperature that is -273 ⁰C or 0K
10. 10. Convert Celsius to Kelvin ɵ⁰C is equal with (ɵ + 273) K Example: What is 27⁰C in Kelvin?? 300K
11. 11. Lets see physics in action!!! Lets Watch video >>>
12. 12. Example
13. 13. Solution
14. 14. Example 3 ? 3 V1 V2 = T1 T2 1.2 1.26 = (24+273) T2 T2 = 311.85 K = 38.85 ⁰C
15. 15. Closure What is the relationship between temperature with Volume?? What is absolute zero define as?? What is Charles’ Law Formula??
