Boyle’s Charle’s Guy-Lussac’s & Combined Gas laws WORKSHEET

  1. A gas occupies 3.5L at 15.9 Kpa. What is the volume at 55.6 Kpa at the same temperature?
  2. A constant volume of oxygen is heated from 100°C to 185°C. The initial pressure is 46.5 Kpa. What is the final pressure?
  3. A sample of 25. L of NH3 gas at 10.°C is heated at constant pressure until it fills a volume of 50. L. What is the new temperature in °C?
  4. An ideal gas occupies 400.ml at 270. Kpa and 65°C. If the pressure is changed to 110. Kpa and the temperature is increased to 100.°C, what is the new volume?
  5. A 600.mL balloon is filled with helium at 250. Kpa. The balloon is released and climbs to an altitude where the barometric pressure is 45.0 Kpa. What will the volume of the balloon be if, during the ascent, the temperature drops from 24. to 5.0°C?
  6. An unknown gas has a volume of 200.L at 320. Kpa and -140.°C. What is its volume at STP?
  7. In an autoclave, a constant amount of steam is generated at a constant volume. Under 145 Kpa the steam temperature is 100.°C. What pressure setting should be used to obtain a 165°C steam temperature for the sterilization of surgical instruments?
  8. A sample of sulfur dioxide occupies a volume of 652 mL at 40.0° C and 720 mm Hg. What volume will the sulfur dioxide occupy at STP?
  9. A 20. L container is filled with helium and the pressure is 150 atm and the temperature is 30.° C. How many 5.0 L balloons can be filled when the temperature is 22° C and the atmospheric pressure is 755 mmHg? (hint: check the pressure units!)
  10. A sample of argon has a volume of 5.0 dm3 and the pressure is 0.92 atm. If the final temperature is 30.° C, the final volume is 5.7 L, and the final pressure is 800. mm Hg, what was the initial temperature of the argon? (hint: look up what a dm3 is)
