1. If the pressure of a 7.2 liter sample of gas changes from 735 torr to 800.torr and thetemperature remains constant, what is the new volume of the gas?2. A gas expands from 4.7 liters to 10.0 liters and at the same time its pressure changesfrom 756 torr to 1.2 atm. If the temperature of the gas at the expanded volume is30.oC, what was the original temperature Celsius of the gas before it expanded andchanged pressure?3. To what temperature (Celsius) must a gas at 50.oC and 107 kPa be heated in order toincrease its pressure to 3.50 atm if the volume of the gas remains constant?4. A gas whose pressure is 1.34 atm occupies a volume of 46.9 liters. This gas isallowed to expand to 65 liters and the temperature remains constant. What is thepressure of the gas at the expanded volume?5. 39.1 milliliters of gas whose temperature if 25oC is heated to 98oC and the pressureremains constant. What is the new volume of the gas now?26. A student collects 450. mL of HCl(g) at a pressure of 100. kPa and a temperature of17 oC. What would be the volume of the HCl at STP?7. If 100. milliliters of a gas, originally at 760. torr, is compressed to a pressure of 120.kPa, and the temperature remains constant, what will the final volume be?8. A volume of 20.0 liters of oxygen is warmed from -30.oC to 85oC. What is thevolume of the gas at 85oC if the pressure is kept constant.9. A gas has a pressure of 1.45 atm when the temperature is 80.oC. What would be itspressure if the temperature is changed to 35oC if the gas is confined to a rigidcontainer whose volume will not change?10. A student collects oxygen gas by water displacement at a temperature of 16 oC. Thetotal volume is 188 mL at a pressure of 92.3 kPa. What is the pressure of oxygencollected?
