If a system is made to undergo a change from an initial state to a final state by adiabatic process only, then

Options

  1. Athe work done is different for different paths connecting the two states.
  2. Bthere is no work done since there is no transfer of heat.
  3. Cthe internal energy of the system will change.
  4. Dthe work done is the same for all adiabatic paths.

Correct answer

D. the work done is the same for all adiabatic paths.
