Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you determine if an object will sink or float in water?

Back

An object will sink in water if its density is greater than 1 g/mL and will float if its density is less than 1 g/mL.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the unit of measurement for density in liquids?

Back

The unit of measurement for density in liquids is grams per milliliter (g/mL).

Front

What is the process of measuring the volume of an irregular object using water called?

Back

The process is called displacement.

Front

What tool is commonly used to measure mass in a science lab?

Back

A triple beam balance is commonly used to measure mass.

Front

If an object has a mass of 30 grams and a volume of 10 mL, what is its density?

Back

Density = 30 g / 10 mL = 3 g/mL.

Front

What happens to the water level in a graduated cylinder when an object is submerged?

Back

The water level rises due to the displacement caused by the submerged object.

Front

What is the density of water?

Back

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

Front

If an object has a density of 0.8 g/mL, will it float or sink in water?

Back

It will float because its density is less than that of water.
