Question

Define Density...??????​

Answer 1

Answer:

$\large{\underline{\underline{\textsf{\maltese{\red{answer}}}}}}$

The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: {\displaystyle \rho ={\frac {m}{V}}} where ρ is the density, m is the mass, and V is the volume.

Dєfínαtíσn σf Dєnsítч :

The density of a substance is defined as the mass of a unit volume of that distance.

If a volume V of a substance has mass M,the density D of the substance is given as

$\bf Density \: = \: \frac{Mass}{Volume} \: or \: D \: = \frac{M}{V}$

Fσr єхαmplє :

( i ) The mass of an iron cube of volume 10 cm³ is found to be 78 g.

Therefore, density of iron = 78 g / 10 cm³=7.8 g cm³

( ii ) The mass of 1 cm³ of water is 1 g,hence density of water = 1 g / 1 cm³ = 1 g cm³

♦ The density of a substance does not change in it's shape or size.
