Q: At which temperature is the density of water maximum?
  • A. 247 K
  • B. 244 K
  • C. 277 K
  • D. 273 K
Correct Answer: Option C - The temperature At 4ºC or 277 Kelvin(K) turns out to be the temperature at which water has the highest density. If we heat it or cool it, it will expand. The expansion of water when we cool it to lower temperatures is unusual, since most liquids contract when they re cooled. At 277K of temperature is the density of water maximum due to anomalous property of water.
