 A graph of pressure versus volume for an ideal gas for different processes is as shown. In the graph curve OC represents

A)  isochoric process

B)  isothermal process

C)  isobaric process

D)  adiabatic process

Correct Answer: D

Solution :

(i) Curve OA represents isobaric process (since pressure is constant) Since, the slope of adiabatic process is more steeper than the isothermal process. (ii) Curve OB represents isothermal process. (iii) Curve OC represents adiabatic process. (iv) Curve OD represents isochoric process (since volume is constant).
