Hello, I have some questions to say true or false.
a) In a P,T,V system always will be true \int P dv \geq W_{out} if the system has friction.
b)In Thermodynamic the work who cross system border is always process function
c)The adiabatic work in Thermodynamic who cross the border in a closed system is independent of process and depends of the final and initial status
d)In a Expansion no reverse it`s true W_{expansion}=W_{useful}+\left|W_{friction}\right| +W_{atmospheric}
3. The attempt at a solution
Well I think a) and c) are true and b) d) are false
Thank you
