Question

In which of the following sets, all the properties belong to same category (all extensive or all intensive)?

A. Mass, volume, specific heat
B. Temperature, pressure, volume
C. Heat capacity, density, entropy
D. Enthalpy, internal energy, volume

Answer 1

The correct answer is D. Enthalpy, internal energy, volume, as they are all extensive properties that depend on the amount of matter present.

Step-by-step explanation:

The question asks to identify which sets consist either entirely of extensive properties or intensive properties. Extensive properties depend on the amount of matter present while intensive properties do not. Let's analyze each set:

• A. Mass, volume, specific heat - Mass and volume are extensive, but specific heat is an intensive property.
• B. Temperature, pressure, volume - Temperature and pressure are intensive properties, but volume is extensive.
• C. Heat capacity, density, entropy - Heat capacity and entropy are extensive properties, while density is intensive.
• D. Enthalpy, internal energy, volume - All of these are extensive properties because they all depend on the amount of matter.

Therefore, the correct answer is D. Enthalpy, internal energy, volume, as they all belong to the category of extensive properties.
