2. RECALL Mix and Match You need to work as a team to match each gas property from Column A with its correct description from Column B.  

3. Mix and Match Column A Column B A. B . C. D. A. B . C. D.

4. Mix and Match Column A Column B A. B . C. D. A. B . C. D.

5. OBSERVE balloon in a bottle

6. Place the bottle upright on a table. Gently pull the balloon membrane downward. Let go of the balloon membrane.

7. Question What happen when I Gently pull the balloon membrane downward? How about when I Let go of the balloon membrane?

8. CONCEPT Pulling down on the balloon membrane attached to a bottle makes the balloon inside inflate because the pressure inside decreases and volume increases. Releasing the membrane deflates the balloon as pressure returns to normal. This shows Boyle's Law: increasing volume decreases pressure, and vice versa.

9. TASK 1 WORD SEARCH Look for 3 words in the word search puzzle below that are related to Boyles law  

10. Problem 1: A gas occupies a volume of 2.5 liters at a pressure of 1.2 atmospheres. What will be the volume if the pressure is increased to 2.4 atmospheres, assuming the temperature remains constant?  

11. Problem 1: A gas occupies a volume of 2.5 liters at a pressure of 1.2 atmospheres. What will be the volume if the pressure is increased to 2.4 atmospheres, assuming the temperature remains constant?  

12.   TASK 2 SCRAMBLED WORDS Rearrange the letters to form the correct words. The definition is given EPRUESRS OVLMUE RIEYSEVNL AILOPRNORTOP

13.   Problem 2: A balloon contains 3 liters of air at a pressure of 1 atmosphere. If the volume of the balloon is reduced to 1 liter, what is the new pressure inside the balloon, assuming the temperature is constant?

14.   Problem 2: A balloon contains 3 liters of air at a pressure of 1 atmosphere. If the volume of the balloon is reduced to 1 liter, what is the new pressure inside the balloon, assuming the temperature is constant?

15.   1. A gas has a volume of 6 liters under a pressure of 0.5 atmospheres. Calculate the pressure required to compress the gas to 2 liters, assuming constant temperature

16. The gas laws are a group of laws that govern the behaviour of gases by providing relationships between the following: The volume occupied by the gas. The pressure exerted by a gas on the walls of its container. The absolute temperature of the gas. The amount of gaseous substance (or) the number of moles of gas.

17. The gas laws were developed towards the end of the 18 th  century by numerous scientists (after whom the individual laws are named). The five gas laws are listed below: Boyle’s Law: It provides a relationship between the pressure and the volume of a gas. Charles’s Law: It provides a relationship between the volume occupied by a gas and the absolute temperature. Gay-Lussac’s Law: It provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas. Avogadro’s Law: It provides a relationship between the volume occupied by a gas and the amount of gaseous substance. The Combined Gas Law (or the Ideal Gas Law): It can be obtained by combining the four laws listed above.

18. Under standard conditions, all gasses exhibit similar behaviour . The variations in their behaviours arise when the physical parameters associated with the gas, such as temperature, pressure, and volume, are altered. The gas laws basically describe the behaviour of gases and have been named after the scientists who discovered them.
