Chapter 11 Practice

A scuba diver’s air tank holds 2.5 L of air at a pressure of 200 atm. If the air is released at a pressure of 1 atm, what volume will it occupy? (Apply Boyle’s Law.)

• 500 L

• 400 L

• 600 L

• 300 L

A syringe contains 50 mL of gas at a pressure of 1.2 atm. If the plunger is pushed in, reducing the volume to 25 mL, what will the new pressure be? (Use Boyle’s Law.)

• 2.4 atm

• 1.2 atm

• 0.6 atm

• 3.0 atm

A weather balloon has a volume of 4.0 L at 95 atm. If it rises to a higher altitude where the pressure is 50 atm, what will its volume be? (Solve using Boyle’s Law.)

• 7.6 L

• 8.0 L

• 7.2 L

• 6.5 L

A gas is stored in a 10 L container at 5 atm of pressure. If the pressure is reduced to 2 atm, what is the new volume of the gas? (Boyle’s Law applies.)

• 25 L

• 20 L

• 15 L

• 10 L

A sealed bag of chips has a volume of 750 mL at sea level (1 atm). When taken to a mountaintop where the pressure is 0.85 atm, what will the new volume of the bag be? (Use Boyle’s Law.)

• 882.35 mL

• 750 mL

• 637.5 mL

• 900 mL

A balloon has a volume of 2.0 L at 27°C. What will its volume be if the temperature rises to 177°C? (Apply Charles’s Law.)

• 4.0 L

• 3.0 L

• 2.5 L

• 5.0 L

A car tire is inflated to 35 L at 270 K. If the tire heats up to 310 K, what will the new volume be? (Use Charles’s Law.)

• 40.19 L

• 37.5 L

• 32.5 L

• 30 L

A hot air balloon has a volume of 500 L at a temperature of 2°C. What will its volume be if the temperature increases to 77°C? (Charles’s Law explains this.)

• 750 L

• 1000 L

• 1250 L

• 1500 L

A soccer ball has a volume of 4,500 mL when stored at 280 K. If it is taken outside on a hot day where the temperature is 320 K, what will its new volume be? (Solve using Charles’s Law.)

• 5,143 mL

• 5,000 mL

• 4,500 mL

• 4,000 mL

A gas-filled container has a volume of 1.8 L at 250 K. If the temperature increases to 500 K, what will the final volume be? (Charles’s Law applies here.)

• 3.6 L

• 2.4 L

• 1.8 L

• 0.9 L
