Question

remy thought that vegetable oil was the least dense substance in this glass. is remy correct? explain why (or why not).

Explanation:

Step1: Recall density - layering principle

Less - dense substances float on more - dense substances.

Step2: Analyze the layering in the glass

In the glass, rubbing alcohol and food coloring are on top of vegetable oil, water and food coloring are below vegetable oil, and corn syrup is at the bottom.

Step3: Determine the least - dense substance

Since rubbing alcohol and food coloring are on the topmost layer, they are the least dense. Vegetable oil is not the least dense.

Answer:

No, Remy is not correct. Rubbing alcohol and food coloring are less dense than vegetable oil as they are on the top - most layer in the glass, indicating that vegetable oil is not the least dense substance.
