What is the symbol for density?
ρ
ρ = density in g/cm 3. The symbol for density is the Greek letter rho, . m = mass in g.
What is the density unit?
Kilogram per cubic meterDensity / SI unitThe kilogram per cubic metre is the coherent SI derived unit of density, defined by mass in kilograms divided by volume in cubic metres. Wikipedia
What is the equation used to calculate density?
d = M/V
density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Who Discovered density?
Density was discovered by a Greek mathematician and engineer named Archimedes. He was born in the city of Syracuse, which was the heart of art, commerce and science, and his father, Phidias, was a mathematician and an astronomer.
Is density a weight?
The key difference between density and weight is that weight is a measure of the amount of matter in an object, whereas density measures the amount of matter in a unit volume.
What is a density in math?
Density is the mass of an object divided by its volume.
Is density a chemical or physics?
Density is a physical property of matter that expresses a relationship of mass to volume. When materials of different densities are put in contact with one another, their densities will determine how they order themselves.
How do you explain density to a child?
Lesson Summary Density measures the mass of an object or substance compared to its volume. The equation we use to find density is: density = mass / volume. If an object is heavy and compact, it has a high density. If an object is light and takes up a lot of space, it has a low density.
What does dense mean in science?
Definition of dense 1a : marked by compactness or crowding together of parts dense vegetation dense traffic. b chemistry : having a high mass (see mass entry 2 sense 1c) per unit volume (see volume entry 1 sense 2) Carbon dioxide is a dense gas.
