Question

Which of the following is an extensive property?

• A. Molar volume
• B. Internal energy
• C. Temperature
• D. Density
• E. Pressure

Hint:

Extensive properties like internal energy depend on the size or amount of the substance, while intensive properties like temperature do not.

Answer 1

The Correct Option is B

- Extensive properties depend on the amount or size of the substance, and they change as the size of the system changes. Examples include mass, volume, and internal energy.
- Molar volume is an extensive property because it depends on the amount of substance present.
- Internal energy is also an extensive property because it depends on the quantity of the system.
- Temperature is an intensive property because it does not change with the amount of substance.
- Density is an intensive property because it is independent of the amount of substance.
- Pressure is an intensive property because it does not depend on the amount of substance in the system.
Thus, the correct answer is Internal energy (B), as it is an extensive property.
