Question 667: Thermodynamics & KTG

Question

During thermodynamic process, the increase in internal energy of a system is equal to the $\mathrm{w}_{0 r k}$ done on the system. Which process does the system undergo?

Accepted Answer

1. First law of thermodynamics:
$ \Delta U = Q + W_{	ext{on}} $
where
$\Delta U$ = change in internal energy,
$Q$ = heat supplied
to
the system,
$W_{	ext{on}}$ = work done
on
the system.
2. Given condition:
$ \Delta U = W_{	ext{on}} $
Comparing with the first law:
$ \Delta U = Q + W_{	ext{on}} \implies W_{	ext{on}} = Q + W_{	ext{on}} $
Cancelling $W_{	ext{on}}$:
$ Q = 0 $
3. Meaning:
If heat transfer $Q = 0$, then the process is
adiabatic
.
