need help with this problem, this is all that is given and what ive done so far
As shown in the figure, a cylinder with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle. I' (gum) When the gas is in the initial state, the volume is 3.00 L, the pressure is 1.00 atm, and the temperature is 300 K. The gas is first warmed at constant volume to a pressure of 2 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally it is compressed isobarically to its initial state. (Due to the nature of this problem, do not use rounded intermediate values in your calculationsincluding answers submitted in WebAssign.) (a) Find the number of moles of the gas. 0.12 / moles (b) Find the temperature of the gas at state B (in K). 600 / K (c) Find the temperature of the gas at state C (in K). 600 / K (d) Find the volume of the gas at state C (in L). 6.00 / L (e) Determine values (in kJ) for Q, W, and AE Q = 0.463 / kJ W = 0 / kJ AEint 0.463 / kJ int for the process A > B.

Knowing the change in internal energy and the work done on the gas, we can use the first law of thermodynamics to determine the heat transferred. kJ (h) Determine values (in kJ) for Q, W, and AE.

Knowing the work done on the gas and the heat transfer for each process of the cycle, how can we determine these quantities for the complete cycle? How can you use the first law of thermodynamics to check your work? kJ Oyk) for the complete cycle A > B > C > A. AE- IntStep by Step Solution
