Worksheet on Boyle’s Law

Show given information, formula, substitution into formula, unit cancellation, and correct answer.

1. A weather balloon has a volume of 0.5 L at a pressure of 1 atm. What volume will the gas in the balloon occupy when the pressure is 0.5 atm if the temperature remains the same?

Answer: 1 L Soln

2. A gas occupies 7.40 L at a pressure of 1.26 atm. What will the pressure of the gas be if the volume is 2.93 L and the temperature remains unchanged?

Answer: 3.18 atm Soln

3. The pressure exerted on a 240. mL sample of gas at constant temperature is increased from 0.428 atm to 0,724 atm. What will the final volume be?

Answer: 142 mL Soln

4. A container with 155 cm³ of chlorine gas exerts a pressure of 22.5 kPa. What will be the pressure if the volume is changed to 90.0 cm³, assuming the same temperature.

Answer: 38.8 kPa Soln

5. A sample of gas occupies 1.00 x 10⁶ mL at 575 mm Hg. If the pressure is changed to 950. mm Hg, what will its volume be if the temperature remains the same?

Answer: 6.05 x 10⁵ mL Soln
