How is qp = Delta(H)? where, qp represents heat at constant pressure.

Dear Student,

Please find below the solution to the asked query.

Refer to the following links:
https://www.meritnation.com/ask-answer/question/how-to-derive-delta-h-qv-from-first-law-of-thermodynamics/thermodynamics/1776867

The derivations for both the relations have been given in the study material also. In case of any doubt, please ask the remaining query in a separate thread.

This is kirchoffs eqn.. at const volume W=0 therefore q=deltaU. hence proved q at const v = deltaU
