Why does water have a maximum density at +4 deg C ? Is water unique in having this peak in density not at an extremity of the temperature range of a single (i.e. liquid in the case of water) state? Is this property of water the single most important reason for life to have evolved on this planet?
If something is denser than water, it will sink. If something is not as dense as water, it will float. At 15 degrees celsius, water is roughly 999 kgs per cubic meter. So, If â¦ a object has a mass of 1000 kgs, and a volume of 20 cubic meters, then its density is 50 kgs per cubic meter, and it will float.owever, the density of a fluid increases as its depth increases and its temperature decreases. For seawater density changes due to composition, depth and temperature ranging from 1,020 to 1,029 kgâ¢m â3 at the surface to 1,050 kgâ¢m â3 or higher. at great depths.
