This question requires the use of the extracts from the tables of thermodynamic properties supplied. A system in equilibrium contains steam at a pressure of 15 bar and a temperature of 450 °C. What is the specific enthalpy of the steam? 3364 J/kg a. b. 3364 kJ/kg c. 2792 J/kg O d. 2792 MJ/kg K O e. 2792 kJ/kg

The Kelvin-Planck and Clausius statements of thermodynamics are equivalent.  In order to proof the equivalence, the process is to demonstrate that _______   A. the violation of the Clausius statement leads to the violation of the  Kelvin-Planck statement   B. the compliance of the Kelvin-Planck statement leads to the compliance  of the Clausius statement   C. the compliance of the Clausius statement leads to the compliance  of the Kelvin-Planck statement   D. the violation of the Kelvin-Planck statement leads to the violation of the Clausius statement

2. An ideal gas (the weight is m kg) in an idealized piston-cylinder assembly undergoes a series of processes from state 1 to states 2, 3 and 4. Each state is at equilibrium. The gas can be modeled as a closed system. Ignore changes of KE and PE. The states are fixed by the following properties in the table: State 1 2 3 4 8 7 9 Note: State 1 to 2 is a constant-temperature process. State 2-3 is a constant-volume process. State 3-4 is a constant-temperature process. (a) Mark the states 1-4 and draw the three processes (1-2, 2-3, 3-4) on the following p-v diagram. p (bar) 4 5 3 1 2 0 p (bar) 1 3 1 6 3 v (m³/kg) 3 1 1 2 2 300K 600K T (K) 300 300 600 600 3 4 5 v (m³/kg) 6 7 8 (b) Use equations and simple texts to explain and answer the questions for the two processes (process 1-2, and process 2-3), respectively. (i) How does the internal energy change during each process: no change, increase or decrease (AU)? (ii) How does the enthalpy change during each process (AH)? (iii) Is the work…
