when liquid water cools the molecules come closer together, water is most dense at 4 degrees Celsius and anything less there is vibrational movement and the hydrogen bonding are more rigid. at this point water expands as it freezes, meaning ice is more dense than water causing it to float.
What else can I help you with?
Does mercury sink?
In water it surely does. It is very dense.
Why do you think water is less dense when frozen and more dense at room temperature?
because ice floats on water
Is room temperature water less dense than cold water?
Yes, generally speaking, room temperature water is less dense than cold water. As water cools, it contracts and becomes denser, which is why cold water is often heavier than warm water.
Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
Is water or carbon dioxide denser?
At room temperature and pressure, water is more dense than CO2. If CO2 is cooled and compressed to a liquid, it is more dense than water.
At what temperature should you keep the water melons so as to get most nutritions?
Water melons, when at room temperature, are most nutritious.
What element is more dense than water?
All of them except for Li, Na, K, and the ones that are gaseous at room temperature.
Are all gases less dense than water?
No, not all gases are less dense than water. For example, gases like chlorine, fluorine, and carbon dioxide are denser than water at room temperature and pressure.
Why does hot water escape to the top in room temperature water?
Hot water is less dense than room temperature water, which is why it rises to the top. As water is heated, its molecules move faster and create more space between them, resulting in lower density. This difference in density causes the hot water to float on top of the cooler water, leading to stratification based on temperature.
What does plutonium do at room temp?
At room temperature plutonium is a solid, radioactive metal, very dense.
Do different temperatures affect water density?
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.
How much does a cubic decimeter of water weight?
At 4 deg C and a pressure of 1 atmosphere, the mass is 0.999972 kilograms. At this temperature, water is at its most dense. At room temperature (20 deg C) the mass is 0.9982071 kg. The weight will, of course, depend on where on earth (or elsewhere) the weight is measured.
