What is the formula for calculating density?

Back

Density = Mass / Volume

Front

If an object has a mass of 10g and occupies a volume of 5cm³, what is its density?

Back

2 g/cm³

Front

What is the density of water in g/ml?

Back

1 g/ml

Front

How does the density of helium compare to the density of air?

Back

Helium is less dense than air.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density increases.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is placed in.

Front

How do you determine the density of an irregularly shaped object using water displacement?

Back

Measure the initial water level, submerge the object, and calculate density using the change in water level for volume.

Front

What is the density of a substance with a mass of 50g and a volume of 25ml?

Back

2 g/ml

Front

List the steps to calculate the density of an object.

Back

1. Measure the mass of the object. 2. Measure the volume of the object. 3. Use the formula Density = Mass / Volume.

Front

What is the significance of density in identifying substances?

Back

Density can help distinguish between different materials, as each substance has a unique density.
