Yes. Hot water expands a little, so that the same mass takes up more room; Therefore, the density decreased.
It's generally true that things expand when heated and contract when cooled. For water, this is true for temperatures about 4 degrees Celsius/39 degrees F. When going below 4C/39F, water begins to form a crystalline structure as it freezes, and expands by about 15% to become ice.

Is room temperature water less dense than cold water?
yes
Why do you think water is less dense when frozen and more dense at room temperature?
because ice floats on water
What difficulties would arise if you defined terms of the density of water?
Yes, the density of water is dependent on its temperature, but the relation is not linear. When cooled from room temperature liquid water becomes increasingly dense, just like other substances. But at approximately 4 °C, water reaches its maximum density. As it is cooled further under ambient conditions, it expands to become less dense.
Is hot water denser than frozen water?
Yes, water is unique in that it is the only substance that expands when frozen. Therefore ice will be less dense in terms of water molecules than room temperature water or heated water
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.
What is most dense ice water or room temperature water?
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.
600ml equels how many pounds?
It depends on the liquid. At room temperature and sea level 600ml of water weighs 600g. 600g is 1.3lbs. If your 600ml is denser than water then it'll be more, if it's less dense it'll be less.
Is fluorine less dense than water?
Fluorine exists as a gas at room temperature and the density is 0.001696g/cm3 at standard temperature and pressure (0 degrees celsius and 1 atm). This is very much lower than the density of water, which is 1g/cm3 for pure water.
Is neon less or more dense than water?
At room temperature, neon, which is an inert gas, is far and away less dense than water. Water, as you know, is a liquid at room temperature, and neon is never found in nature on earth as anything but a gas. A link can be found below.
Hexane solube in water?
Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
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.
Can room temperature carbonated water hold less salt?
yes it can
