1. What is the volume of gas at 2.00 atm and 200.0 K if its original volume was 300.0 L at 0.250 atm and 400.0 K.
2. A gas balloon has a volume of 106.0 liters when the temperature is 45.0 oC and the pressure is 740.0 mm Hg. What will its volume be at 20.0 oC and 780 .0 mm Hg pressure?
3. A gas sample occupies 3.25 liters at 24.5 oC and 2.0 atm. Determine the temperature at which the gas will occupy 4250 mL at 1.50 atm.
4. 2.00 liters of hydrogen, originally at 25.0 oC and 750.0 mm Hg, are heated until a volume of 20.0 liters and a pressure of 0.50 atmospheres is reached. What is the new temperature?
