Use the combined gas law to solve the following problems:
1) If I initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?
2) A gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299 K. If I raise the temperature to 350 K and lower the pressure to 1.5 atm, what is the new volume of the gas?
3) A gas that has a volume of 28 liters, a temperature of 45 ? 0? C, and an unknown pressure has its volume increased to 34 liters and its temperature decreased to 35 ? 0? C. If I measure the pressure after the change to be 2.0 atm, what was the original pressure of the gas?
4) A gas has a temperature of 14 ? 0? C, and a volume of 4.5 liters. If the temperature is raised to 29 ? 0? C and the pressure is not changed, what is the new volume of the gas?
