Density

Front

What is density?

Back

Density is defined as mass per unit volume of a substance, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

What are the two main components that make up density?

Back

Density is made up of mass and volume.

Front

How do you calculate the density of an object?

Back

Density can be calculated using the formula: Density = Mass / Volume.

Front

What is the unit of measurement for density in liquids?

Back

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

Front

Which liquid is generally the most dense?

Back

Syrup is often cited as one of the most dense liquids.

Front

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

Back

The water level rises by an amount equal to the volume of the submerged object, demonstrating the principle of displacement.

Front

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

Back

The density is 5 g/mL, calculated using the formula Density = Mass / Volume.

Front

What is the principle of buoyancy related to density?

Back

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

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases because the liquid expands.

Front

What is the significance of the density of a substance in real-world applications?

Back

Density is crucial in determining whether substances will float or sink, which is important in fields like engineering, meteorology, and oceanography.
