Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant.

Some unknown gas undergoes a polytropic process, pV^1.5 = constant, the initial pressure, p1, is 1 bar, and the initialvolume, V1, is 1 m3. We also know the final volume, V2, is 4 m3. Please determine 1) the final pressure of the gas, p2, inbar; and the total work done by the gas, W, in kJ; 2) judge the direction of energy flow for the work: into the system or outof the system.
