The density formula is ρ = m/V: density = mass ÷ volume, with mass in kilograms (kg), volume in cubic metres (m³) and density in kg/m³. The Calculating Density notes cover this in full.
Mass is found by rearranging the density equation to m = ρ × V. The Calculating Density notes cover this in full.
Density is measured in kg/m³ or g/cm³. The States of Matter and Density notes cover this in full.
Density is the mass per unit volume of a material, telling us how much matter is packed into a given space. The Calculating Density notes cover this in full.
Specific heat capacity is the amount of energy required to raise the temperature of one kilogram of a substance by one degree Celsius, measured in J/kg°C. The Understanding Specific Heat Capacity notes cover this in full.
Specific heat capacity is measured in joules per kilogram per degree Celsius (J/kg°C). The Understanding Specific Heat Capacity notes cover this in full.
To calculate density, convert to SI units, find the volume, then divide mass by volume. The Calculating Density notes cover this in full.
The density of aluminium is 2700 kg/m³, meaning each cubic metre of aluminium has a mass of 2700 kg. The Calculating Density notes cover this in full.
