During a lab investigation a scientist heats a solid substance. The scientist observes that the solid has two different melting points. The scientist is able to separate the two resulting liquids. Which statement best classifies the original solid substance

This question is incomplete; the options are:

A. It was an atom.

B. It was a mixture.

C. It was an element.

D. It was a compound.

The answer is B. It was a mixture.

Explanation:

A mixture is a substance which contains two or more different substances (with differing properties) that can be easily separated from each other. Each component of a mixture retains their individual properties, hence, they can be separated via physical means.

According to this question, a scientist is conducting an investigation where it was observed that the solid involved has two melting points. After heating the solid, the scientist is able to separate the two resulting liquids. This suggests that the original solid substance was a MIXTURE because it could be separate using heat.
