thanks for watching
why did u take the average temp for calculation of Cp ?
We can also calculated the Heat transferred in this process by using the equation dq = nCp dT and integrate this eqn from 500K to 1000K. What''s wrong in this method.
Yes. I have the same doubt.

dQ is not equal to Cp dT as it is not a constant pressure process

However why don't we calculate delta U by integrating Cv dT as heat capacity is not constant and function of temperature ?

  4. O In a reversible compression, 1 mol of an ideal gas in a piston cylinder device undergoes a pressure increase from 1 bar to P. Temperature increases from 500K to 1000K. Compression path is PVA1.5- constant. Heat Capacity is Find final pressure

  5. State State 2: P ba, lOOOK bar,Sook P V 1 . S Also, PV=nRT =const. V= nRT 1- S T' = cons t ant . 12
