Density of liquid
It should be a note
Also tell its definition
Answers
Liquid water has a density of about 1 kg/dm3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm3.
Answer:
A material's density is defined as its mass per unit volume. Put another way, density is the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" an object has in a unit volume (cubic meter or cubic centimeter). Density is essentially a measurement of how tightly matter is crammed together. The principle of density was discovered by the Greek scientist Archimedes, and it is easy to calculate if you know the formula and understand its related units.
Density Formula
To calculate the density (usually represented by the Greek letter "ρ") of an object, take the mass (m) and divide by the volume (v):
ρ = m / v
The SI unit of density is kilogram per cubic meter (kg/m3). It is also frequently represented in the cgs unit of grams per cubic centimeter (g/cm3).
How to Find Density...
In studying density, it can be helpful to work a sample problem using the formula for density, as mentioned in the previous section. Recall that though density is indeed mass divided by volume, it is often measured in units of grams per cubic centimeter because grams represent a standard weight, while cubic centimeters represent the volume of the object.
For this problem, take a brick of salt measuring 10.0 cm x 10.0 cm x 2.0 cm, which weighs 433 grams. To find the density, use the formula, which helps you determine the amount of mass per unit volume, or:
ρ = m / v
In this example, you have the dimensions of the object, so you have to calculate the volume. The formula for volume depends on the shape of the object, but it's a simple calculation for a box:
v = length x width x thickness
v = 10.0 cm x 10.0 cm x 2.0 cm
v = 200.0 cm3
Now that you have the mass and volume, calculate the density, as follows:
ρ = m / v
ρ = 433 g/200.0 cm3
ρ = 2.165 g/cm3
Thus, the density of the salt brick is 2.165 g/ cm3.
