Water is most dense at 4C (around 39F). Any colder or warmer, and the water's density begins to decrease. This is due to the shape and polarity of the water molecules. The very electronegative oxygen and the lone pair make the molecule into the bent shape (v-shape) with O being the "point" of the v. At 4C, these molecules have stacked into and "filled in" the space between the legs of the "V." As it gets colder, the molecules form a lattice that is more rigid in nature, and eventually a solid that is less dense than liquid water (which is why ice floats, rather than sinks, in water). As 4C water gets warmer, the molecules also move out of the space between the legs due to the extra energy and movement included in a higher temperature.

Is mercury the heaviest naturally occurring element?
No, the three densest elements under ordinary conditions are osmium, iridium and platinum, in that order. Please see the link. *************************** However, mercury is the densest liquid at room temperature.
What substance has a high density?
The densest chemical element is osmium with a density of 22,59 g/cm3 at room temperature.
What wood soaks up water the least?
Most likely hickory it's the densest wood i know of.
What 2 ways can you change density of water?
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
What is the densest cold salt water warm salt water cold fresh water warm fresh water?
Cold Salt Water is the densest. When there is less heat in a liquid, the particles are closer together. The salt also saturates the water and makes it even denser. That's why boats float better in Cold Salt Water than in Warm Fresh Water. P.S. Next time, put commas between the options. -------------------------------------------------------------------------------------------------------- Sources: Grade 8 Science
What is the densest fluid present on earth?
The densest liquid at room temperature is Mercury which is 13.5 times heavier than water.
Is fresh water salt water or ice water densest?
salt water is densest
Explain the fact that the temperature of the ocean at great depth is very constant the year round at the temperature of about 4C?
Because water is densest at 4C, so it will sink to the bottom of the ocean.
What temperature is 39 degrees celsius?
Around four. 4 degrees C is actually 39.1 in Fahrenheit. It is also the densest point of water.
When is water its densest?
when rocks are thrown in it
When is the water densest?
About 4 degrees centgrade.
What temperature in the solid phase has the greatest water density?
In the liquid phase, it is 4o C. seeing how water only expands as it becomes ice, i think 0 degrees celcius is the densest
What is the most dense form of water?
Liquid water is the densest form.
Where would you find the densest water?
4 degrees celsius
Where is the densest ocean water generally found?
deep zone
How do temperature and salinity relate to deep-current movement?
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
If you poor 3 liquids into a jar will the densest sink to the bottom?
Yes the densest liquid will go to the bottom, just as the second densest will go to the middle and the lightest of the 3 will be on top. However many different liquids you place in a container, it will act in the same manner as water and oil, the oil will be on the bottom and the water on top.
