Colton has an ice cube that has a mass of 4 grams. He places it in a sealed container and then puts it in the microwave on high. The ice cube melts after a few seconds. He removes the sealed container with the melted ice cube and checks the mass again.

Which sentence BEST describes what Colton discovers?

• The mass of the melted ice cube was less than 4 grams.

• The mass of the melted ice cube was more than 4 grams.

• The mass of the melted ice cube remained the same at 4 grams.

• The mass of the melted ice cube could not be determined
