Density 1

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

What happens to objects with a density less than 1 g/cm³ when placed in water?

Back

They float.

Front

What happens to objects with a density greater than 1 g/cm³ when placed in water?

Back

They sink.

Front

What is a balance used for?

Back

A balance is used to measure the mass of an object.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

Why do helium balloons rise?

Back

Helium balloons rise because helium is less dense than air.

Front

What is the formula for calculating the volume of a rectangular object?

Back

Volume = Length × Width × Height.
