Parts and their functions
- Density of water vs temperature (ताप के साथ जल का घनत्व) — From 0 °C to 4 °C water contracts on heating; above 4 °C it expands, like most liquids.
- Maximum density at 4 °C (4 °C पर अधिकतम घनत्व) — About 1000 kg m⁻³. Ice is less dense, so it floats.
- Why fish survive winter (मछलियाँ सर्दी में क्यों बचती हैं) — Surface water cooled below 4 °C becomes lighter and stays on top, freezing first; the ice insulates the water at about 4 °C below.
