Anomalous Expansion of Water

State the vol...

Question

State the volume changes observed when a given mass of water is heated from $0^{\circ}$ to $10^{\circ}$ . Sketch a temperature-volume graph to show the behaviour.

Open in App

Solution

When a given mass of water is heated from 0°C to 4°C, it contracts, i.e. its volume decreases.
On heating from 4°C to 10°C, it expands, i.e. its volume increases.
