Maximum Water Density Temperature
The density of water is unique because it is maximum at a specific temperature, unlike most other substances which become densest in their solid state.
- Water reaches its maximum density at approximately 4 degrees Celsius.
- In Kelvin, this temperature is approximately 277.15 K.
- The provided option 277 K is the closest approximation to this value.
Anomalous Expansion of Water
This phenomenon, where water is densest at 4°C (277.15 K) and becomes less dense as it cools further towards 0°C (273.15 K), is known as the anomalous expansion of water.
- Below 4°C, water expands as it cools.
- Ice (solid water) is less dense than liquid water, which is why ice floats.
Therefore, the temperature at which the density of water is maximum is closest to 277 K.
