2. Pre-Activity: CHARLES’ LAW DEMONSTRATION

3. 6 Presentation title 20XX Guide Questions 1. What will happened when the balloon was placed in a hot water?

4. 7 Presentation title 20XX 2. How does gas in a balloon act when heated?

5. 8 Presentation title 20XX 3. What can you conclude about what happened to the balloon when water is cold?

6. OBJECTIVES 1. Explain the relationship between volume and temperature at a constant pressure of a gas. ​ 2. Solves Charles’ Law word problems. 3. Give practical application of Charles’ Law. 9 Presentation title 20XX

7. 1. Volume – is defined as the space occupied within the boundaries of an object in three-dimensional space.

8. 2. Temperature – it is a degree of hotness or coldness measured by a thermometer with a numerical scale.

9. 3. Kelvin – is the SI unit of thermodynamic temperature.

10. 13 Charles Law is an experimental gas law. It explains how gases tend to expand when heated.

11. ACTIVITY: WHICH IS WHICH

12. 1. When the temperature increases, the volume increases too. 2. It gathers information both from the outside world and form the inside of the body. 15 Presentation title 20XX

13. 16 1. When the temperature increases, the volume increases too.

14. 1. If the temperature is increased, the volume will be decreased forcing the gas particles to move closer to one another. 2. The volume of a gas is directly proportional to its absolute of gas and pressure remain constant. 17 Presentation title 20XX

15. 18 2. The volume of a gas is directly proportional to its absolute of gas and pressure remain constant.

16. 1. It processes information to determine the best response. 2. It presents the direct relationship of temperature and volume at constant pressure. 19 Presentation title 20XX

17. 20 2. It presents the direct relationship of temperature and volume at constant pressure.

18. 1. It processes information to determine the best response. 2. It presents the direct relationship of temperature and volume at constant pressure. 21 Presentation title 20XX

19. 22 2. It presents the direct relationship of temperature and volume at constant pressure.

20. 23 Presentation title 20XX A gas expands when its temperature increases. It contracts when temperature decreases. 2. It sends information to muscles, glands and organs so they can respond correctly.

21. 24 A gas expands when its temperature increases. It contracts when temperature decreases.

23. Charles’ Law of Gases

24. 27 Presentation title 20XX A balloon has a volume of 785 mL at 21 ºC. If the temperature drops to 0ºC, what is the new volume of the balloon?

28. 31 Presentation title 20XX When the temperature increases, the volume increases too .

29. 32 Presentation title 20XX If the pressure is increased, the volume will be decreased forcing the gas particles to move closer to one another.

30. 33 Presentation title 20XX If the pressure is increased, the volume will be decreased forcing the gas particles to move closer to one another.

31. 34 Presentation title 20XX Charles’ Law presents the direct relationship of temperature and volume at constant pressure.

32. 35 Presentation title 20XX Charles’ Law presents the direct relationship of temperature and volume at constant pressure.
