Density Mass Volume Review 2022

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 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. Conversely, it will sink if its density is greater.

Front

What unit is commonly used to measure mass in the metric system?

Back

The gram (g) is the standard unit of mass in the metric system.

Front

What is the volume of an object?

Back

Volume is the amount of space an object occupies, typically measured in cubic centimeters (cm³) or liters (L).

Front

What happens to an object with a density less than 1 g/cm³ when placed in water?

Back

An object with a density less than 1 g/cm³ will float in water.

Front

If an object has a mass of 200g and a volume of 50cm³, what is its density?

Back

Density = Mass / Volume = 200g / 50cm³ = 4 g/cm³.

Front

What is the significance of helium being less dense than air?

Back

Helium balloons rise because helium is less dense than the surrounding air, creating an upward buoyant force.

Front

What instrument is used to measure mass?

Back

A balance or scale is used to measure mass.

Front

What is the density of water?

Back

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