A piston-cylinder device contains 0.1 kg of a certain gas (R = 300 J/kg.k, Cv=810J/kg.k, Cp = 1180 J/kg.k) initially at 3 bar and 30 °C. The gas is first expanded at aconstant pressure to 0.05 m³. Then, again expanded Isometrically to 2 bar and finallycompressed Polytropically to the initial pressure. Draw the PV diagram of the cycle andthen determine:I.The boundary work of the entire cycle (W). Is this a practical cycle?Internal energy change (AU) during the polytropic process.II.III.Heat lost or gained (Q) during the isobaric process.

This is a Thermodynamics question. Please explain nicely. Considering variable specific heats, find the entropy change of a piston cylinder assembly containing airas an ideal gas and going through the following process: V1=1m3T1=27 C V2=1.7m3T2= 327 C
Relate between the entropy with the Clausius statement of the second thermodynamics law. [Note: The answer must include appropriate equations]
1 mol of an ideal gas initially at 300 K and 1 bar undergoes a three-step mechanically reversible cycle in a closed system. In step 12, pressure increases isothermally to 5 bar; in step 23, pressure increases at constant volume; and in step 31, the gas returns adiabatically to its initial state. Take CP = (7/2)R and CV = (5/2)R. (a) Sketch the cycle on a PV diagram. (b) Determine (where unknown) V, T, and P for states 1, 2, and 3. (c) Calculate Q, W, ΔUt, and ΔHt for each step of the cycle
COMPLETE SOLUTION. FINAL ANSWER ARE IN ENGLISG SYSTEMS. DRAW A DIAGRAM IF NECESSARY. A gaseous Ammonia actuates a Carnot power cycle in which the respective volumes at the four corners of the cycle, starting at the beginning of the isothermal expansion, are V1 = 12, V2 = 15, V3 = 330.25 and V4 = 264.20. Determine (a) the overall expansion ratio and (b) the thermal efficiency.
