Question

Please help me, thanks. A cylinder contains oxygen gas (O2 ) at a pressure of 2.40 atm. The volume is 4.00 m L, and the temperature is 300 K. Assume that the oxygen may be treated as an idealgas. The oxygen is carried through the following processes: (1) Heated at constant pressure from the initial state (state 1) tostate 2, which has 420 K (2) Cooled at constant volume to 250 K (state 3). (3) Compressed at constant temperature to a volume of4.00 m (state 4). (4) Heated at constant volume to 300 K, which takes the system back to state 1. Calculate Q for each of the four processes. Please help me, thanks.
