Density Calculations 1

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in units like g/cm³ or kg/m³.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find mass using density?

Back

Mass = Density × Volume.

Front

What is the formula to find volume using density?

Back

Volume = Mass / Density.

Front

If an object has a mass of 10 kg and a volume of 2 m³, what is its density?

Back

Density = 10 kg / 2 m³ = 5 kg/m³.

Front

What units are commonly used for density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

If two objects have the same density, what can we infer about their mass and volume?

Back

If two objects have the same density, their mass-to-volume ratio is the same, but their actual mass and volume can differ.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because it expands.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.
