1. | A gas has a starting pressure of 780mm-Hg and 70 degrees Celsius, with an unknown starting volume. The gas is able to expand and itâ€™s final volume was 100 ml, the final pressure was 750mm-Hg and the final temp was 50 degrees Celsius. What was the initial volume in mL? |
2. | What is the temperature in Kelvin when a gas that occupies 1L at 15 degrees Celsius is compressed to .5L? |
3. | 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? |
4. | A sample of gas occupies 15L at 300 degrees kelvin and 350kPa. What is the pressure in kPa if the temperature rises to 500 degrees kelvin and the volume to 30L? |
5. | A 700 ml sample of helium is warmed from 60 to 80 degrees Celsius. What is the new volume in mL of the sample if the pressure remains as a constant, of 5 atm. |
6. | If a gas is cooled from 290 to 250 degrees kelvin and the volume is kept at a constant volume of 780ml.What was the initial pressure in mm-Hg if the final pressure is 810 mm-hg? |
7. | A gas is cooled from 350 to 300 degrees kelvin, with a constant volume of 5L. What would the final pressure of the gas be in mm-Hg if the initial pressure measures at 850 mm-hg? |
8. | 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? |
