Question

An object has a mass of 100 grams and the volume of 20 centimetre . What is its density?

Answer 1

Given :-

• Mass = 100 grams

• Volume = 20cubic.cm

To find

• The density of object

According to the formula

Density = Mass of object / Volume of object

Density = 100/20

Density = 5 g/cm³

★ Density of object = 5g/cm³

Extra information :-

●Density is defined as the mass of substance per unit volume .

●SI unit of density is kilogram per cubic metre ( kg/cm³) (It is big unit of density)

● Smaller unit of density called gram per centimetre cube (g/cm³)

● Density is also used to determine the substance will float or sink in the water .

● When the density of substance is more than density of water hence it will sink ,

On the other hand , When the density of substance is less than density of water it will float.

An object has a mass of 100 grams and the volume of 20 centimetre . What is its density?

${\underline{\huge{\mathbf{\color{red}{Given}}}}}$

• mass of an object = 100grams
• volume of an object = 20 centimeter cube

${\underline{\huge{\mathbf{\color{yellow}{to \:find}}}}}$

• density of an object = ??????

${\underline{\huge{\mathbf{\color{green}{formulae \: used}}}}}$

density= mass of an object / volume of an object

${\underline{\huge{\mathbf{\color{purple}{answer}}}}}$

density = 100/20 gram/cm cube

$density = 5 g/cm^3$

• Mass is a measure of the amount of matter in an object.
• Mass is usually measured in grams (g) or kilograms (kg).
• Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains
• The SI unit of volume is the cubic meter (m3).
• The density, of a substance is its mass per unit volume
• Density is commonly expressed in units of grams per cubic centimetre.
