answer question 3: a), b) and c) An ideal gas, initially

answer question 3: a), b) and c)

An ideal gas, initially at 29C and 105kPa, with Cp,=7R/2 and Cv=5R/2 undergoes the following cyclical process in a closed system. In a mechanically reversible process, there is first an adiabatic compression to 600kPa, then a constant pressure cooling of 600kPa to 29C, and finally an isothermal expansion to its original state. (a) Sketch the PV diagram the process path for this cycle. (3) (b) Calculate the w,q,U and H (in J ) for each of the process. (5+5+5+5)=(20) (c)Calculate the overall w,q,U and H (in J) for the cycle. (4)
