Water exhibits anomalous expansion between 0°C and 4°C. When water is heated from 0°C to 4°C, its volume decreases (and density increases). It reaches its maximum density (and minimum volume) at 4°C. When heated from 4°C to 10°C, water expands like most substances, and its volume increases. Therefore, as water is heated from 0°C to 10°C, its volume first decreases (from 0°C to 4°C) and then increases (from 4°C to 10°C).
When water is heated from 0°C to 10°C, its volume
