1. for an adiabatic process dH is zero. Is it true for both reversible and irreversible process? In adiabatic expansion from 1L to 2L via reversible and irreversible processes then dH should be zero. Is it correct?

yes dH=0 alwways for a adiabatic pressure.

it is defined as a process having dH=0 is adiabatic not in reverse manner.

but for reversible and irreversible (for both dH=0) work done arw diff and thus change in internal energies are diff

i.e final temps are diff.

NO SINCE dH IS CHANGE IN ENTHALPY IN ADIABATIC PROCESS Q=0 WHERE Q IS HEAT FLOW AND IN ADIABATIC REVERSIBLE

Q=dH THEREFORE IN ADIABATIC REVERSIBLE dH=0 BUT IN ADIABATIC IRREVERSIBLE ONLY q=0 AND NOT dH=0
