Question

When camping with your family, you boil a pot of water over a campfire. What physical and chemical changes take place during this process? What evidence of a chemical change do you observe?

a) True
b) False

Answer 1

Boiling water over a campfire involves physical and chemical changes. The physical change is the change of water from liquid to gas, while the chemical change is the combustion of the wood in the campfire.

Step-by-step explanation:

Boiling water over a campfire involves both physical and chemical changes. The physical change is the change of water from liquid to gas as it reaches its boiling point. This is a physical change because no new substances are formed and the water can be condensed back into liquid form.

The chemical change that takes place is the combustion of the wood in the campfire. The wood undergoes a chemical reaction with oxygen in the air, producing heat, light, carbon dioxide, and other combustion products. This is evidenced by the flames and smoke that are observed during the campfire.
