Question

Enthalpy and temperature are?

• A. Both extensive properties
• B. Both intensive properties
• C. Extensive and intensive properties, respectively
• D. Intensive and extensive properties, respectively

Hint:

Remember that extensive properties} like enthalpy change with the amount of substance, while intensive properties} like temperature remain the same regardless of the amount of substance.

Answer 1

The Correct Option is C

Enthalpy is an extensive property, which means it depends on the amount of substance in a system. Extensive properties are proportional to the size or quantity of the system. Enthalpy, being a measure of the total heat content of a system, increases with the amount of substance present.
Temperature, on the other hand, is an intensive property, meaning it is independent of the amount of substance in the system. Intensive properties are not affected by the size of the system. Temperature remains the same for any given state of a substance, regardless of how much is present.
Therefore, the correct answer is that enthalpy is an extensive property and temperature is an intensive property.
- Extensive properties depend on the amount of substance present. Examples include mass, volume, and energy.
- Intensive properties do not depend on the amount of material present. Examples include temperature, pressure, and density.
Thus, the correct answer is extensive and intensive properties, respectively.
