ACTIVITY 2:
How will the unknown parameter/quantity behave in the following situations? Choose among volume/pressure/temperature will increase, decrease, or remain the same.
1. A sample of nitrogen, N2, occupies 45.0 mL at 27°c and 600 torr. Describe its pressure if it was cooled to —73°c while the volume remains constant.
2. A sample of oxygen, 02, occupies 32.2 ml at 30°c and 452 torr. Describe the volume at —70°c and the same pressure.
3. A sample of ammonia is found to occupy 0.250 L under laboratory conditions of 27°c and 0.850 atm. Describe the pressure of this sample if the volume becomes 0.538 L at O°c.
4. A sample of gas has a volume of 30.0 mL at a pressure of 6.5 psi. Describe the volume of the gas at a pressure of 11.0 psi at constant temperature.
5. A sample of carbon dioxide, C02, occupies 0.300 L at 10°c and 750 torr. Describe the temperature if the volume of the gas becomes 0.321 L and 750 torr.
