What does density measure?

How much matter fits in a unit of volume

Which formula is used to calculate density?

density=massvolume\text{density} = \frac{\text{mass}}{\text{volume}}

What symbol represents density in the formula ρ=mV\rho = \frac{m}{V}?

ρ\rho

How do you rearrange the density formula to find mass?

m=ρ×Vm = \rho \times V

How do you rearrange the density formula to find volume?

V=mρV = \frac{m}{\rho}

What is the main unit for density?

kg/m³

Which state of matter has the highest density?

Solids

Why do gases have the lowest density?

Particles are spread far apart

Why do solids have high density?

Particles are tightly packed together

A material has mass 84 kg and volume 0.075 m³. What is its density?

1120 kg/m³

What happens to density if you have more of the same material?

Density stays the same

If you double the volume of a material, what happens to its mass and density?

Mass doubles, density stays same
