MCQ
Which of the following is a slow process
- ✓Isothermal
- BAdiabatic
- CIsobaric
- DNone of these
✓
Answer
Correct option: A.
Isothermal
a
isothermal processes are necessarily slow as they require heat transfer to remain at the same temperature which is done by being in thermal equilibrium with some reservoir. $A$ process will be isothermal only if it happens on timescales larger than the timescale required for effective heat transfer.
