Density

Front

What is density?

Back

Density is defined as mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

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

Front

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

Back

An object with a density greater than that of water will sink when placed in water.

Front

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

Back

An object with a density less than that of water will float when placed in water.

Front

What is the density of water at 4°C?

Back

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

Front

If a brick sinks in water and a wooden block of the same size floats, what can be inferred about their densities?

Back

The brick has a higher density than the wooden block.

Front

What is the least dense liquid among common liquids?

Back

Oil is generally considered to be the least dense liquid among common liquids.

Front

How do you determine if an object is denser than water?

Back

You can determine if an object is denser than water by placing it in water; if it sinks, it is denser; if it floats, it is less dense.

Front

Calculate the density of an object with a mass of 14 g and a volume of 2 cm³.

Back

The density is 7 g/cm³ (Density = Mass/Volume = 14g/2cm³).

Front

Calculate the density of a paper clip with a mass of 9 g and a volume of 3 cm³.

Back

The density is 3 g/cm³ (Density = Mass/Volume = 9g/3cm³).
