Yes. When water freezes, it becomes less dence and floats. When warm, or room temperature, it is liquid and is more dense. This is a rare quality among substances, where most do the opposite and become more dence when they freeze.
You can measure it, and there are tables giving the density of pure water at various temperatures.
will density of water is equal to density of steam at high pressures and temperatures
The density of ultrapure water is not affected.
Yes, one example is the different temperatures associated with water and with ice.
yes it does...but to b more specific, ask the question the other way around "does water temp affect density?"....ABSOLUTELY
Salt will increase the density of water at the same temperatures.
The density of water changes at different temperatures. As temperature goes up, density goes down.
Generally, barring unusual temperatures / pressures the density of water is 1 g / mL The density of water at sea level pressure and 4C temperature is exactly 1 g/mL, at different temperatures it is always less. At different pressures things become more complicated.
no of course it doesnt, gosh
It depends upon the temperatures and purity of the two quantities of water. If they are both at the same temperature and both have the same purity, they will both have the same density as density does not depend upon the volume, but the substance itself. If they are at different temperatures, or have different purities, then they will have different densities, but which would be greater would depends upon which has which temperature and which purity.
hot water takes longer @$$

Yes, water density will affect an object's ability to float.
will density of water is equal to density of steam at high pressures and temperatures
The density of ultrapure water is not affected.

If the water is hot, (at boiling point) it will boil, if the water is cold, ( at freezing point) it will freeze.
