Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find the volume of an irregular object using water displacement?

Back

Volume = Final water level - Initial water level.

Front

If an object has a mass of 50 g and occupies a volume of 10 mL, what is its density?

Back

Density = 50 g / 10 mL = 5 g/mL.

Front

What happens to an object with a density less than that of water when placed in water?

Back

It will float.

Front

What happens to an object with a density greater than that of water when placed in water?

Back

It will sink.

Front

What units are commonly used to measure volume?

Back

Milliliters (mL) and cubic centimeters (cm³).

Front

What is the mass of an object if its density is 2 g/mL and its volume is 5 mL?

Back

Mass = Density x Volume = 2 g/mL x 5 mL = 10 g.

Front

What is the principle of buoyancy?

Back

An object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases.
