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.
What else can I help you with?
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.
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.
Is ammonia more dense or less dense than air?
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
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.
What liquid is less viscous yet heavier than water?
Mercury is a liquid that is less viscous but heavier than water. Mercury is a dense liquid metal at room temperature, making it heavier than water, which is less viscous than water due to its lower viscosity.
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.
Which compounds tend to be liquids or gases at room temperature due to their Specific Heat?
Compounds with lower specific heat tend to be liquids or gases at room temperature, as they require less energy to increase their temperature. This means they are more likely to exist in a less dense state compared to compounds with higher specific heat, which are typically solids at room temperature.
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
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.
Does mercury sink?
In water it surely does. It is very dense.
