Density Pre-Lab Activity

Front

What is the equation for calculating density?

Back

density = mass/volume

Front

If two cubes have the same volume, can they have different densities?

Back

Yes, because their mass might be different.

Front

Why do some substances float on water?

Back

They are less dense than water.

Front

If two cubes have the same mass, will they also have the same density?

Back

No, they may have different densities.

Front

Put the liquids in order from most dense to least dense: 4, 3, 2, 1

Back

4, 3, 2, 1

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume.

Front

What units are commonly used to express density?

Back

g/cm³ (grams per cubic centimeter) or kg/m³ (kilograms per cubic meter).

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases as the substance expands.

Front

What is the relationship between mass and volume in determining density?

Back

Density is directly proportional to mass and inversely proportional to volume.

Front

How can you determine if an object will sink or float in water?

Back

If the object's density is greater than that of water, it will sink; if less, it will float.
