Question

Identify each transition in this flowchart as a chemical change or a physical change.

1) Chemical change
2) Physical change

Answer 1

In the flowchart, the fire in the fireplace is a chemical change, while warming water is a physical change.

Step-by-step explanation:

In this flowchart, we have two processes to identify as either a physical change or a chemical change:

1. A fire is raging in a fireplace: This is an example of a chemical change because the wood in the fireplace is undergoing combustion, which is a chemical reaction.
2. Water is warmed to make a cup of coffee: This is an example of a physical change because the water is changing state from a liquid to a gas, but its chemical composition remains the same.
