Question

Did Thomas observe a physical change or a chemical change when he put the water in the freezer?

Answer 1

Thomas observed a physical change in the water because the water changed state of matter from a liquid to a solid.

Answer 2

Answer:

Thomas observed a physical change

Step-by-step explanation:

Water does NOT change chemically when it turns into ice.

It changes forms of liquid to solid, temporarily, and can be easily made back into liquid form by melting.

Nothing was created nor destroyed.

Therefore, it is a physical change because the physical properties of the water changed, not its H2O element.
