1. BALLOON in a BOTTLE Fill up the balloon with enough air. Put the inflated balloon on the opening of the bottle with water. Remember not to let go of the balloon yet without the go signal from the teacher. After putting the balloon on the opening of the bottle, slowly release the air from the balloon.

2. What happened when you released the air to the bottle with water? BALLOON in a BOTTLE 2. What will most likely happen if you cover the opening of the other bottle?

14. ROBERT BOYLE He was an Anglo-Irish chemist who was able to investigate the relationship between pressure and volume at constant temperature.

15. ROBERT BOYLE He used a J-shaped tube apparatus, which is closed on one end. In his experiment, he trapped air in the tube with liquid mercury. He measured the volume of the trapped air and the difference in the heights of the mercury columns in the two arms of the tube. As he poured successive amounts of mercury into the open end of the tube, he found out that the volume of the trapped air decreases.

16. States that pressure is inversely proportional to the volume at constant temperature P 1 V 1 =P 2 V 2 BOYLE’S LAW

17. 1. A gas occupies 12.3 L at a pressure of 40.0 mmHg. What is the volume when the pressure is increased to 120.0 mmHg? Try This Out!

18. P 1 = 40mmHg P 2 = 120 mmHg V 1 = 12.3 L V 2 = 4.1 L

19. 2. Fluorine gas exerts a pressure of 906 torr. When the pressure was changed to 1.50 atm, its volume is 350 mL. What was the original volume? Try This Out!

20. P 1 = 906 torr P 2 = 1.5 atm V 1 = 440 mL V 2 = 350 mL

24. 1.00 L of a gas at standard temperature and pressure is compressed to 0.473 L. What is the new pressure of the gas? Calculate the volume that will be occupied by 208 cm 3 of propane if its pressure changes from 24 atm to 48 atm. A gas occupies a volume of 4.5 L at a pressure of 760 mmHg. If the volume is decreased to 2.0 L while the temperature remains constant, what will be the new pressure of gas in atm? SEATWORK
