Question
An ideal gas undergoes four different processes from thesame initial state (Fig.). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1, 2, 3 and 4 whichone is adiabatic.

  1. 4
  2. 3
  3. 2
  4. 1
✓

Answer

  1. 2

Explanation:

4 is isobaric process, 1 is isochoric. out of 3 and 2, 3 has the smaller slope (magnitude) hence is isothermal. Remaining process 2 is adiabatic.
