The correct answer is
277
Water Maximum Density Kelvin Temperature
Understanding the temperature at which water achieves its highest density is key. Water behaves uniquely compared to most substances.
- The maximum density of pure water occurs at approximately $ 4^{\circ}C $.
- To find the equivalent temperature in Kelvin, we use the conversion formula: $ T(K) = T(^{\circ}C) + 273.15 $.
- Applying this: $ 4 + 273.15 = 277.15 K $.
- Therefore, water has its highest density at nearly 277 Kelvin. This corresponds to Option C.
