Density
What is density? Density is the amount of mass per unit volume of a material Matter is made of particles (atoms or molecules) that have mass. The density of a material depends on the masses and the number of particles packed into a given volume.
Calculating density D=density, units are g/cm3 or g/mL m = mass, units are in g v = volume, units are in cm3 or mL
Solving for volume Solving for volume Irregular objects can be solved using a graduated cylinder and water Regular objects can be used by measuring and formulas
Density and materials Density does not change for an object, even if it’s volume and mass changes Densities of some common materials Water is always 1g/mL
What does density depend on? Mass of particles More mass, greater density Distance between particles Greater the distance between the atoms/molecules, the smaller the density Density of a gas is usually much less than the density of a solid or liquid
