Science review Physical and Forces

A teacher poured three liquids into a glass. Then the teacher added three objects to the glass. The diagram shows where each substance stopped. Which liquid is most likely corn syrup?

• Liquid Z because corn syrup is more dense than water

• Liquid Y because corn syrup is more dense than water

• Liquid Y because corn syrup is less dense than water and more dense than a sponge

• Liquid Z because corn syrup is less dense than water
