An ideal gas at 300 K occupies a volume of 0.5 m3 at a pressure of 2 atm. The gas expands adiabatically until its volume is 1.2 m3. Next, the gas is compressed isobarically to its original volume. Finally, the pressure is increased isochorically until the gas returns to its initial state. Represent the change on the P-V diagram. Determine the temperature at the end of each transformation; and the work done during the cycle. Assume g = 1.4.

1.	An ideal gas at 300 K occupies a volume of 0.5 m3 at a pressure of 2 atm. The gas expands adiabatically until its volume is 1.2 m3. Next, the gas is compressed isobarically to its original volume. Finally, the pressure is increased isochorically until the gas returns to its initial state. Represent the change on the P-V diagram. Determine the temperature at the end of each transformation; and the work done during the cycle. Assume g = 1.4.
Answer» An ideal gas at 300 K occupies a volume of 0.5 $m^{3}$ at a pressure of 2 atm. The gas expands adiabatically until its volume is 1.2 $m^{3}$ . Next, the gas is compressed isobarically to its original volume. Finally, the pressure is increased isochorically until the gas returns to its initial state. Represent the change on the P-V diagram. Determine the temperature at the end of each transformation; and the work done during the cycle. Assume g = 1.4.
