8.1 Internal Structure and Density
Notes
$$\rho=\frac{m}{V}$$
- Water's density is 1,000 kg/m³ (1 g/cm³).
- Objects less dense than a fluid float in it.
Practice
A 2 kg object has volume 0.001 m³. Its density:
$\displaystyle \frac{2}{0.001}$.
An object with density 800 kg/m³ in water will:
Less dense than water.
Cutting a block of wood in half changes its density:
Mass and volume both halve.
