Water is different from other compounds, it is most dense as a liquid at 4C.
No, George Washington was the first president of the United States.
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.
Water is an exception to this rule as it becomes less dense when it freezes and forms ice. This is due to the unique arrangement of water molecules in ice compared to liquid water, causing it to expand and become less dense.
Ice is less dense than liquid water, and liquid water is more dense than water in the gaseous state.
Particles do make objects denser than they normally may be. For example, if you add particles of salt to water, the water will become more dense. Alternately, if you filter impurities out of water it will become less dense.

When you cool water its density will increase as it will become more dense.
Because the water gets colder isn't that obvious!
the molecules spread out and become less dense

denser, the buoyancy of objects is one way you can tell the water gets less dense.
