1. A cylinder contains 12 L of oxygen at 20oC and 15 atm. The temperature is raised to 35oC , and the volume is reduced to 8.5 L. What is the final pressure of the gas in atmospheres? Assume that the gas is ideal.
2. A gas expands from an initial volume of 0.40m3 to a final volume of 0.62m3 as the pressure increases linearly from 110 kPa to 230 kPa. Find the work done by the gas.
