Front

What is a convection cell?

Back

A circular pattern of moving fluid.

Front

What happens to an object's density when its mass increases but volume stays the same?

Back

Density increases.

Front

If you have 5 cubic centimeters (cm³) with a mass of 20 g, what is the density?

Back

4 g/cm³.

Front

What is the relationship between cubic centimeters (cm³) and milliliters (mL)?

Back

1 cm³ = 1 mL.

Front

Which formula correctly represents density?

Back

Density = mass ÷ volume.

Front

Define density.

Back

Density is the mass of an object divided by its volume.

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter).

Front

How does temperature affect the density of most substances?

Back

As temperature increases, density usually decreases.

Front

What is the formula to calculate mass if density and volume are known?

Back

Mass = Density × Volume.

Front

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

Back

It generally decreases.
