Seawater, then pure @ 4 degrees C.
The question is ambiguous, controlling factor of what? Specific gravity will change according to temperature (all other things being equal) Salinity will not change with temperature. Water will is most dense at about 4 degrees Celsius, and will become less dense at higher and lower temperatures (to a point)
It's most dense at 4 degrees celsius. Get any lower and it takes up more volume. As a general rule, chemicals get denser as they get colder.
its according to what other temperature of water you are comparing it to. water is densest at 4 degrees C so water that is colder then 4 degrees C is technically less dense then water at 4C. in that case the warmer water is denser. but if you mean warm water to be >4C and cold water to be colder then warm water, but not below 4C, then cold water is more dense then warm water. but the question you are probably trying to get answered would have an answer of cold is denser
As a general rule of thumb for most substances as the temperature increases the density decreases. There are a few well-known exceptions to the rule; for example the density of liquid water between 0 degrees and four degrees Celsius actually increases with temperature to a maximum at 4 degrees (after which it starts decreasing again). Even more widely known is that liquid water at 0 degrees Celsius is more dense than ice at the same temperature; this is very unusual, as for most substances the solid phase is more dense than the liquid phase.
Most substances become more dense as their temperatures decrease. The bonds between each atom gets close and stronger, thus harder to break apart. However, water has a special property that, at 4 degrees Celsius, the atoms are the most dense. As water gets colder, the atoms get further apart, so when water is 0 degrees Celsius (Freezing point) then the atoms are less dense than water at 4 degrees Celsius. When a substance is less dense than the liquid it`s placed in, it would float. That`s why ice water would float on water.
More dense than what? I presume you mean is it more dense at that temperature than at lower temperatures. The answer is no, it gets denser at lower temperatures, all the way down to 4 degrees centigrade. Then it gets less dense again.
4 degrees Celsius.
A density current forms when more dense seawater moves toward less dense seawater.

Water expands at 4 degrees Celsius because this is the temperature at which it reaches its maximum density. As water cools below 4 degrees Celsius, it begins to expand and become less dense, eventually transforming into ice. This unique property of water is due to the hydrogen bonding between water molecules.
It's at its most dense at 4 degrees Celsius. Below that it becomes less dense until it freezes and above 4 degrees Celsius it also gets progressively less dense (due to its expansion).
At 1000 degrees Celsius, osmium would be in its solid state as it has a melting point of 3033 degrees Celsius. Osmium is a very dense and hard metal known for its blue-gray appearance.
Density current
Water has the greatest density at 4ºC or 39.2ºF
at -4 degrees celsius if the water is a solid state of matter,it will turn into a liquid
