Hello!

The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.

The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.

In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.

If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.

Have a nice day!
