Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

Front

What is the formula for calculating density?

Back

density = mass / volume

Front

Which liquid is the least dense?

Back

Oil is the least dense liquid compared to water, syrup, and a plastic bottle.

Front

What tool is used to find mass?

Back

A triple beam balance is used to measure mass.

Front

What property of matter is determined by dividing its mass by its volume?

Back

Density is the property of matter determined by dividing mass by volume.

Front

If an object has a mass of 10 grams and a volume of 2 cm³, what is its density?

Back

Density = mass / volume = 10 g / 2 cm³ = 5 g/cm³.

Front

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

Back

If the mass increases while the volume remains the same, the density of the object increases.

Front

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

Back

If the volume increases while the mass remains the same, the density of the object decreases.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases because they expand.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is related to the density of the object compared to the density of the fluid.
