1. A gas occupies a volume of 458 mL at a pressure of 50 kPa and temperature of 295 K. What is the pressure of the gas if the volume is changed to 477 mL and the temperature remains constant?
2. A certain gas has a volume of 100 mL, at 400 K and a pressure of 2 atm. What will be the new volume of the gas at 6 atm, assuming the temperature remains the same?
3. The volume of a syringe is 0.5 mL and the pressure is 3 atm, when the plunger is at the bottom of the syringe. The syringe is then sealed and forced to the 10 mL mark. What is the pressure inside of the syringe?
4. A tire at a volume of 10 liters of air and a pressure of 300 kpa, is compressed to 5 liters. What is the new pressure in the tire in atm?
