Questions and Answers

What is the formula for calculating density?

$Density = Mass + Volume$

$Density = rac{Volume}{Mass}$

$Density = Mass imes Volume$

$Density = rac{Mass}{Volume}$ (correct)

What is the unit of density mentioned in the notes?

g/cm³

kg/m³ (correct)

L/kg

m³/kg

Which symbol is likely used to represent density in the notes?

ρ (correct)

Density

A measure of how much matter is packed into a given space.

Units of Density

The standard unit for density is kilograms per cubic meter (kg/m³).

Symbol for Density

The Greek letter 'rho' (ρ) is often used as the symbol for density.

Relationship between Density, Mass, and Volume

Density is directly proportional to mass and inversely proportional to volume. This means if mass increases, density increases; if volume increases, density decreases.

Study Notes

Density

Density is the mass of a substance per unit volume
Represented by the symbol 'ρ' (rho)
Formula: Density = Mass/Volume
Units: kg/m³
If the volume of an object is 'V', and the mass is 'm', then density (ρ) = m/V
Density is always positive
Density describes how tightly packed the particles of a substance are
