Detailed example to solve questions related to polytropic process

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 ?
