Question

Which of the following is an example of an intensive property?

• A. Temperature
• B. Mass
• C. Volume
• D. Total energy

Hint:

Quick identification rule:
• Intensive properties do not change with amount.
• Extensive properties increase with system size. Examples: \[ \text{Temperature, density, pressure} \rightarrow \text{Intensive} \] \[ \text{Mass, volume, energy} \rightarrow \text{Extensive} \]

Answer 1

The Correct Option is A

Concept: Physical properties are classified into:
• Intensive properties: Independent of the amount of substance.
• Extensive properties: Depend on the amount of substance.

Step 1: Analyze each given property.

• Temperature \( \rightarrow \) Independent of quantity \( \Rightarrow \) Intensive
• Mass \( \rightarrow \) Depends on quantity \( \Rightarrow \) Extensive
• Volume \( \rightarrow \) Depends on quantity \( \Rightarrow \) Extensive
• Total energy \( \rightarrow \) Depends on quantity \( \Rightarrow \) Extensive

Step 2: Select the intensive property.
Only temperature remains unchanged regardless of system size. Therefore: \[ \boxed{\text{Temperature}} \]
