Work in reversible adiabatic and irreversible adibatic is same is it possible because if it is possible than work would be a state function ....

work in reversible adiabatic and irreversibpossible than work would be a state function

dQ=0 for adiabatic process. And from the 1st law of thermodynamics, dQ=∆U + dW So, for adiabatic process dW= -∆U which is a point function and doesn't depend on path.

In both cases work done is different

Reversible work means the max work that could be obtain from a process . In adiabatic process,work done is a state function . So until the state is fixed the work done will be same for both reversible or irreversible process .

as it is derived for adiabatic process...so work done comes same here and it is state function in this process

Now if dq is zero then

then the process is adiabatic. so du= dw
- Like(0)
du is a state function hence dw should also be a state function

first read this...but as from 1st law of thermodynamics it is state function in adiabatic process
