Which of these is an extensive property of a substance?

Step 1: Define the Problem

Identify the key components of the question that need to be addressed: Determine which property of a substance is extensive.

Step 2: Break Down the Problem

Divide the problem into smaller, manageable parts:

• Understand the difference between extensive and intensive properties.
• Identify examples of each type of property.

Step 3: Apply Relevant Concepts

• Extensive Properties: These depend on the amount of substance present. Examples include mass, volume, and total charge.
• Intensive Properties: These do not depend on the amount of substance. Examples include density, temperature, and boiling point.

Step 4: Analysis, Verify and Summarize

• Analyze the definitions: Extensive properties change when the size of the sample changes, while intensive properties remain the same regardless of sample size.
• Verify examples: Mass and volume are extensive because they change with the amount of substance.

Final Answer

An extensive property of a substance is one that depends on the amount of substance present, such as mass or volume.
