A sample of gas, initially with a volume of 1.0 L, undergoes a thermodynamic cycle. Find the work done by the gas on its environment during each stage of the cycle described below. (Enter your answers in J.)   (a) First, the gas expands from a volume of 1.0 L to 4.5 L at a constant pressure of 7.0 atm.  J (b) Second, the gas is cooled at constant volume until the pressure falls to 1.0 atm.  J (c) Third, the gas is compressed at a constant pressure of 1.0 atm from a volume of 4.5 L to 1.0 L. (Note: Be careful of signs.)  J (d) Finally, the gas is heated until its pressure increases from 1.0 atm to 7.0 atm at a constant volume.  J (e) What is the net work done by the gas on its environment during the complete cycle described above?  J

What is the net work Wnet,s = ΣWs done by the gas in this process and What is the heat QH taken from the hot reservoir? Please answer both, its my last question remaining!

Please help me

Problem #2: For this problem, one mole of a diatomic ideal gas is taken around a reversible cycle by starting at pressure P, volume V, and temperature T, then in an isochoric process 1 increasing pressure to 6P, then in an isobaric process 2 increasing its volume to 21V, then another isochoric process 3 back to a pressure P, and finally in an isobaric process 4 back to P, V, T.   Find the temperature of this gas at the end of process 1, 2, and 3 in terms of the original temperature T.                     Find the internal energy change in process 1 and in process 2 in terms of P and V.               Find the heat transfer in process 1 and in process 2 in terms of P and V.

This is a thermodynamics question! Please consider all equations for thermo. Please show all steps and ensure the answer is in the correct units!   NO TUTOR HAS GOTTEN THIS RIGHT :( Answers are very inconsistent

For the two PV diagrams below, find the net work done on the gas during the process indicated by the path. (Enter your answers in J.) (a) P (10*Pa) 6.00 4.00 2.00 V (m³) 2.00 4.00 6.00 -400008 |× J (b) P(10°Pa) 6.00 4.00 2.00 V (m³) 2.00 4.00 6.00 800008

The second image shows how I worked this out. I don't see how I'm getting this wrong. Thank you for your help.
