B- Show why with equations Cy can be calculated using the enthalpy while Cp using the internal energy? (6 Marks)

how did you convert the atm pressure mm Hg?

B- Prove that Pvc for adiabatic process of perfect gas

2. The gas expanding in the combustion space of a reciprocating engine has an initial pressure of SO bar and an initial temperature of 1623*C. The initial volume is 50000 mm' and the gas expands through a volume ratio of 20 according to the law pV constant. Calculate w and AU Take R= 270 J/Kg K and C, = 800 J/Kg K. Assume n 1.38

Identify, which is not correct from the diagram Select one: O a. 2-3 and 4-1 = constant pressure process O b. 1-2,2-3,3-4,4-1= path O c. 1-2-3-4-1= Cyclic process O d. 1-2 and 3-4= constant Temperature process

i need the answer quickly

1. R = 8.314 J mol–1 K–1, find the equivalent in calories per mole per Kelvin

How does the My and Mz become 0? is there any explanation?
