When a student heats a liquid on a burner, the portion of the liquid that first begins to warm will **become less dense**. As the liquid heats up, its temperature increases, causing the molecules to move more vigorously and spread apart, which results in a decrease in density. This less dense, warmer liquid tends to rise, while the cooler, denser liquid sinks.
