A square metal plate has a surface area of $1.5\text{ m}^2$ . What is this area expressed in square centimetres ( $\text{cm}^2$ )?

To determine the volume of 50 small identical glass beads, a student pours $30\text{ cm}^3$ of water into a measuring cylinder and then adds all the beads. The water level rises to $42\text{ cm}^3$ . What is the volume of a single glass bead?

Why does ice float on liquid water, whereas most other substances sink when they freeze?

A uniform block of material has a mass of $450\text{ g}$ and a volume of $150\text{ cm}^3$ . If this block is cut into two unequal pieces, the density of the smaller piece will be:

A block of copper has a density of $8960\text{ kg m}^{-3}$ . If the block has a total mass of $448\text{ kg}$ , calculate the volume of the block.

V = \frac{m}{\rho}

$15,000\text{ cm}^2$

$150,000\text{ cm}^2$

Ice traps high-pressure air bubbles during the freezing process

The density of water is independent of its temperature

Ice molecules have less mass than liquid water molecules

Water molecules form an open hexagonal lattice as they freeze, increasing the volume
