2) 1 kg of air undergoes a thermodynamic cycle consisting of three processes. Process 1-2: constant volume while heat is added, Process 2-3: constant temperature expansion, Process 3-1: constant pressure compression, at state 1, the temperature is 300 K, and pressure is 100 kPa. At state 2, the pressure is 200 kPa. Employing the ideal gas law and assuming constant specific heat at room temperature: a. Determine the temperature at state 2, in K. b. Determine the specific volume at state 3, in m'/kg. e. Sketch the cycle on P-v diagram

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.
