- 1.A gas in a balloon that has a volume of 5 L is at a pressure of 0.7atm. The gas is able to expand at a constant temp of 10 degrees Celsius until the pressure is at 0.5atm. What is the final volume of the box?
- 2.A 3.5 L sample of an unknown gas is at a pressure of 900kPa. If the pressure increases to 1013 kPa at a constant temperature of 150 degrees kelvin, What will the new volume be?
- 3.A gas occupies 15 L at a pressure of 80 mm-Hg. What is the volume when the pressure is increased to 525 mm-Hg?
- 4.A gas occupies 10 L at an unknown pressure. What is the initial pressure, if the final volume is 5L and the pressure is 5atm?
- 5.. A gas occupies 15 L at a pressure of 5 atm. What is the volume when the pressure is increased to 10 atm but the temperature remains at 273 degrees kelvin?
- 6.A gaseous sample of carbon dioxide occupies a volume of 3.27 L at a temperature of 20 degrees Celsius. If the pressure remains constant, what is the temperature in Kelvin if the volume lowers to 3L?
- 7.What is the temperature in Kelvin when a gas that occupies 1L at 15 degrees Celsius is compressed to .5L?
