what is the temperature of water at highest density?

Answer 1

4 °C

"... at 4 °C, just above freezing, water reaches its maximum density, and as water cools further toward its freezing point, the liquid water, under standard conditions, expands to become less dense."

Answer 2

Answer 4

The correct answer is 4 deg. Celcius.

Water is an exceptional compound that has a lower density in the solid phase than the liquid phase (i.e., ice floats on water). This is actually due to the ion nature of water in the liquid phase, which packs the molecules tighly together. As water starts to freeze, the solidifying bonds create an ice crystalline structure that actually forces the water molecules apart. This process begins at 4 C and ends at 0 C, the freezing point. Therefore, the highest density of water is at the coolest point in the liquid phase, 4 C.

Answer 5

water attains a maximum density at 4 degree centigrade. above the 4 degree temperature, the water molecules expands due to temperature increase. hence density will decrease.

in case of cooling below 4 degree centigrade, the water molecule arrangements changes in such a way that it occupies more space than water molecules at liquid phase. hence density decreases with cooling. this is not the case when comparing other substances.

Answer 6

It's 4 Deg C, since water when reaches below 4 deg, it expands rather than contracting, this property is called Anomalous expansion of water. And since density of a substance is inversely proportional to Volume (Density decreases with increase in Volume). Therefore water has highest Density at 4 deg C and lowest Volume. :)

Answer 7

The highest density occurs at 4 degrees celsius. Water which gets cooled below this point begins to expand which is why ice for instance floats not sinks.

Water continues to become more dense as it cools until just above the freezing point. I can't remember the exact temperature off-hand, but I believe it is very near 33.5 to 34 degrees Fahrenheit. Below that water begins to expand and once it has frozen, its volume increases approximately 10%...that's why ice floats...less dense than the water it came from! Cool, huh?

Answer 9

Liquid water increases in density as it cools. During the phase change to ice, the density drops markedly. This characteristic is one of the peculiarities of water.

However, the density of ice will continue to increase as it is cooled further. I don't know if it ever exceeds the density of liquid water approaching the phase change.

Answer 10

... high heat of vaporization, high specific heat, and highest density at 4 degrees C. ... Most substances get continually more dense as their temperature is reduced
