Is hot water denser than room temperature water?

Hot water is less dense than room temperature water. If I fill a tank with cold water and then add hot water, I could feel with my hand that the warmer water would be toward the top. Which is denser, hot water or cold water? Cold water is denser (thicker) than hot water; it sinks in room-temperature water while the hot water floats to the top.

What temperature is water the most dense?

Water is at its most dense (smallest volume per unit mass) at 4 degrees Celsius or 39.2 degrees Fahrenheit. At this temperature, 1 cubic centimeter or milliliter of water weighs approximately 1 gram. Why is liquid water more dense than ice?
