Question

Identify isothermal and adiabatic process in the following diagram

Answer 1

As slope of an adiabatic curve is greater than the slpoe of an isothermal curve, therefore,
In (figure)(a): 1 is isothetmal , 2 is adiabatic
In (figure) (b), 1 is aidabatic , 2 is isothermal
In (figure) (c ), 1 is adiabatic, 2 is isothermal
