Isochoric Process - Practice Questions & MCQ

Isochoric Process- A Thermodynamic process in which volume remains constant is known as the Isochoric Process.

In this process P and T changes keeping P constant. So Gay-Lussac’s law is obeyed in this process.

  Key points in the Isochoric Process 

• Its Equation of state is given as

               or  

• P-V Indicator diagram for an isobaric process

       Its PV graph has slope= infinity (i.e )

The above Graph represents an Isochoric increase in pressure at volume V.

 The P-V diagram for this process is a  line is parallel to the pressure line.

• Specific heat of gas during Isochoric process is given by

• The bulk modulus of elasticity during Isochoric process is given by

• Work done in Isochoric process-

• Internal energy in Isochoric process

• Heat in Isochoric process

From FLTD 

But

So

• Examples of Isochoric process-

1. Heating of water in a pressure cooker (Valve closed)
