To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.

mash [69]

Answer:

The density.

Explanation:

The density is an intensive property of fluids, defined as mass divided by volume.

This property is directly related to the intermolecular forces that are present in the substance: the stronger the intermolecular forces, the higher the density will be, and viceversa. Therefore, organic fluids usually have lower densities than water, because <u>the intermolecular forces in organic fluids are not as strong as in the intermolecular forcer in water</u> (water has very stable hydrogen bonds, whereas organic fluids have van der Waals, weaker than hydrogen bonds).

The liquid that has the lower density will be the the liquid that is on the top layer. In this case, the organic compound tert-butyl methyl ether will be on top of water.

Density Practice
Angelina_Jolie [31]

Answer:

1) mass and volume

2)  float.

3) Sink

4) Apples

5) Cannonball

Explanation:

1) Density is based on the mass and volume of a material.

2) A material or an object with low density than water or liquid tends to float.

3) A material or an object with high density than water or liquid tends to sink.

4) The apples in the water have less density as they are floating in the water.

5) The cannonball is more dense than the ocean water and the ball sink in the less density water.
