Question
Chapter 2, Problem 95A
Interpretation Introduction
Interpretation: The reason for rangers at national parks to know about physical and chemical changes needs to be explained.
Concept Introduction: When a substance changes its appearance or change in the state takes place and there is no change in its chemical composition, the change is said to be physical. On the other hand, when there is a change in the chemical composition of a substance or a new substance is formed after a
Expert Solution & Answer
Explanation of Solution
In a chemical change, a new substance is formed. In a physical change, the physical appearance of a substance changes, but its chemical composition remains the same. Rangers in the national park need to know the difference between a chemical and a physical change to understand the properties of matter. By knowing the chemical properties, it is easy to understand how a sample interacts with other matter. These properties can help in identifying the unknown specimen.
