1. Some air at 276 kPa occupies 32.4 m3. What is its absolute pressure if its volume is doubled at constant temperature?
2. Some helium at 17.5 psi gauge pressure occupies 35.0 ft3. What is the volume at 32.4 psi if the temperature is constant?
3. Some carbon dioxide has a density of 6.35 kg/m3 at 685 kPa gauge pressure. What is the density when the gauge pressure is 355 kPa if the temperature is constant?
4. We have 435 in3 of nitrogen at 1340 psi gauge pressure at 75°F. What is the volume at 1150 psi gauge pressure at 45°F?
5. We have 755 m3 of carbon dioxide at 344 kPa at 25°C. Find the temperature if the volume is changed to 1330 m3 at 197 kPa.
