Density is defined as:
The mass per unit volume of a material
Density is related to mass and volume by the following equation:
ρ = density, measured in kilograms per metre cubed (kg m−3)
m = mass, measured in kilograms (kg)
V = volume, measured in metres cubed (m3)
ex : -
Gases, for example, are generally less dense than solids because the particles in a gas are more spread out (same mass, over a larger volume)
The units of density depend on what units are used for mass and volume:
If the mass is measured in g and volume in cm3, then the density will be in g/cm3
If the mass is measured in kg and volume in m3, then the density will be in kg/m3
volume to calculate density
Derive the formulae of Sphere?
1. What is the density of an object with a mass of 570g and a volume of 2280 cm cube?
2. What is the principle of density? dont write formula. just the principle behind it.
3. Which metal has the highest density?
4. find out the density of a cube of sugar which weighs 12 grams and measures 2cm on a side?
5.What is the density of water if it has a mass of 1160 kg and a volume of 1m3?
