MCQ
Which of the following is a slow process
  • Isothermal
  • B
    Adiabatic
  • C
    Isobaric
  • D
    None 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.
