Question

when poured into water, glycerol (also a liquid) falls to the bottom of the beaker. which of the following is a true statement?
an object that floats in water will always float in glycerol
the glycerol is less dense than the water.
the water is more dense than the glycerol
an object that floats in glycerol will always float in water.

Explanation:

When glycerol sinks in water, this means glycerol has a higher density than water. For an object to float in a liquid, its density must be less than the liquid's density. If an object floats in water, its density is less than water's density, and since glycerol is denser than water, the object's density will also be less than glycerol's density, so it will float in glycerol. The other options are incorrect: glycerol is denser (not less dense) than water, water is less dense (not more dense) than glycerol, and an object that floats in glycerol could have a density between water and glycerol, meaning it would sink in water.

Answer:

A. An object that floats in water will always float in glycerol
