Does water expand when getting warmer?
It depends on the temperure of the water. Water actually reaches maximum density at 4 degrees centigrade. It expands or gets less dense as it increases in temperature above that.
As water gets denser how does it moves?
Water increases in density until 4 degrees Celcius, when its density starts to decrease again due to hydrogen bonding. (see Wikipedia.org for more.) As water moves away from the equator, it gives off heat. As it cools, its density increases.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
Does water affect density of wood?
yes water can increase the density of water as wood has the power to absorb water and so the density of water is drastically increased
How much density does water have?
Pure water has a density of 1,000 kg/m3

Why does all the water in a lake have to be cooled to 4 degrees Celsius before water can be cooled below 4 degrees Celsius?
Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum. Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!
Does water contract or expand when it is cooled?
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%
As water is cooled what happens to the density?
it becomes more dence
What degree Celsius does water reach maximum density?
Water reaches maximum density at 4 degrees Celsius
Where does the water go when it reaches land?
When water reaches land it can flow across the land until it reaches rivers, lakes, streams or the sea.
What is the density if water is cooled fron 4 degrees celcius to 0 degrees celcius?
decreases
As water is cooled from 4 degrees C to 0 degrees C its density?
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
When water is further cooled down its volume starts increasing and its density decreases why is it so?
Hydrogen bonding !
What happens to the density of an iron bar when it is cooled?
1.) A sample of chlorine gas is compressed. 2.) A sample of water is frozen. 3.) A diamond is submerged in water. 4.) A lead weight is carried up a mountain. 5.) An Iron bar is cooled.
