A liquid changes color as it cools and becomes solid. How can you confirm
Bas_tet [7]

Answer: Hello, There! your answer is Below.

D. The formation of a solid from a liquid confirms that a physical

change took place.

Explanation:

The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together. Attractive forces begin to trap particles, and the crystals of a solid begin to form.

Hope this helps you!!!

Have a great day!!!
