a scientist is studying the liquid shown here. she thinks the liquid is a mixture. describe an investigation she could do to determine whether the liquid is in fact a combination of substances.

Explanation:

To determine if the liquid is a mixture, the scientist can perform a distillation. Heat the liquid. If it is a mixture, different substances will boil at different temperatures and can be separated and collected. For example, if it's a mixture of water and alcohol, alcohol (lower boiling point) will vaporize first, be condensed, and collected separately. If it's a pure substance (not a mixture), it will boil at a single constant temperature.

Answer:

The scientist can perform distillation. Heat the liquid. If it's a mixture, substances with different boiling points will vaporize at different times, be condensed, and collected separately. If it's a pure substance, it will boil at a single constant temperature.
