Frequently Asked Questions
Why does ice float if water is expanding?
Water has anomalous expansion. It contracts from 0°C to 4°C, reaching maximum density at 4°C. Below 4°C it expands, making ice less dense than water, so ice floats. This unique property allows aquatic life to survive under ice in frozen ponds.
How much do buildings expand in India's hot climate?
A 10-story building approximately 30 meters tall can expand by 5 to 10 centimeters between winter and summer due to thermal expansion of concrete and steel. This is why buildings have expansion joints.
Can thermal expansion cause safety issues?
Yes. Inadequate accommodation of thermal expansion can cause railway track buckling, road cracking, pipe bursting, and building damage. Modern engineering codes require designs to account for expected thermal expansion.
