Thermodynamics

In cyclic process is delH zero?

@SiddharthaGhosh Yes as we know delta H = U + PV , here U , P,V all are state functions means only depend on final and initial state , so yes delta H is zero in cyclic process.

@YouKnowwhere i have one doubt , PV is work and so path function to ? PV non zero to ?

@SiddharthaGhosh Think by first law of thermodynamics i.e U = Q + W and w =(  )integration of pv and so when we make temperature constant the U became zero and total heat become equals to work same like that when we make pressure constant from quantity of work P comes out and then total heat quantity beacame equal to entropy that is H =Q =U+P(DELTA(V) ). (don't forget work is negative of Pv not +PV ).
