Question

A. It is a physical change, where some of the intensive and extensive properties will change
B. It is a chemical change, where both the intensive and extensive
C. It is a physical change, where both the intensive and extensive properties will not change
D. It is a chemical change, where some of the intensive and extensive properties will change

Answer 1

The correct answer is: D. It is a chemical change, where some of the intensive and extensive properties will change.

When wood burns, it undergoes a chemical change as it reacts with oxygen and produces new substances (such as ash, carbon dioxide, and water vapor). During this process, both extensive properties (such as mass and volume) and intensive properties (such as density and color) can change.
