Density Flashcardzi Practice 1

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How can density help identify substances?

Back

Density can help determine whether a substance is gold or another metal, as different materials have unique densities.

Front

If two liquids have the same volume but different weights, what can be inferred about their densities?

Back

The heavier liquid has a higher density.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

A box has a mass of 50 grams and occupies a volume of 100 cm³. What is its density?

Back

0.5 g/cm³.

Front

What is the density of a cube that weighs 4 grams and has a volume of 2 cm³?

Back

2 g/cm³.

Front

If an object has a density of 1 g/cm³, what does that imply about its buoyancy in water?

Back

It will float, as it has the same density as water.

Front

What happens to the density of a substance if its mass increases while its volume remains constant?

Back

The density increases.

Front

What is the relationship between density and temperature for most substances?

Back

As temperature increases, density typically decreases due to expansion.

Front

How does the density of ice compare to liquid water?

Back

Ice is less dense than liquid water, which is why it floats.
