Which among the following is NOT an extensive property?
Which among the following is NOT an extensive property?
Show Hint
A simple trick: If you split a system in half, extensive properties (like volume and mass) are halved, while intensive properties (like pressure, temperature, and concentration) remain exactly the same!

- Mass
- Volume
- Pressure
- Internal energy
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Sort the two kinds of property.
An extensive property grows with the amount of stuff. An intensive property stays the same no matter how much stuff you have.
Step 2: Test each one.
Mass, volume and internal energy all get bigger when you add more matter, so they are extensive.
Step 3: Find the odd one.
Split a gas container in half and the pressure in each half is unchanged. Pressure does not depend on amount, so it is not extensive.
\[ \boxed{\text{Pressure}} \]

Top Questions on Thermodynamics
- The difference of temperature in a material can convert heat energy into electrical energy. To harvest the heat energy, the material should have:
- JEE Main - 2025
- Physics
- Thermodynamics
- Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process, \( PV = \text{constant} \), while in an adiabatic process \( PV^\gamma = \text{constant} \). Here, \( \gamma \) is the ratio of specific heats, \( P \) is the pressure and \( V \) is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below:- JEE Main - 2025

- A poly-atomic molecule (C\(_3\)R, \(C_v = 4R\), where \(R\) is gas constant) goes from phase space point A (\(P_A = 10^4 \, \text{Pa}, V_A = 4 \times 10^{-3} \, \text{m}^3\)) to point B (\(P_B = 5 \times 10^4 \, \text{Pa}, V_B = 6 \times 10^{-7} \, \text{m}^3\)) to point C (\(P_C = 10^4 \, \text{Pa}, V_C = 8 \times 10^{-3} \, \text{m}^3\)). A to B is an adiabatic path and B to C is an isothermal path. The net heat absorbed per unit mole by the system is:
