Answer 2

⚡⚡⚡⚡⚡ ANSWER ⚡⚡⚡⚡⚡



⭐ When a substance is heated its volume increases and as a result density decreases.

⭐ There is an exception, that is water. When water is heated its volume decreases and as a result density increases. This unusual expansion of water is often termed as anomalous expansion of water.

⭐ FACT - Water, when cooled, first contracts in volume as do other liquids, but below 4°C, it starts expanding and continues to do so till the temperature reaches 0°C, the point at which it freezes into ice.
