Yes, hot water is less dense than cold water. This occurs because as the particles move faster when the water is heated, they begin to spread further apart. As a result, there is more space in between the particles, resulting in less density.

∙ 7y agoThis is due to thermal expansion which affects most substances. The heat increases the volume and so reduces the density. However, the anomalous behaviour of water between 0 and 4 degrees C is contrary to this. Water is more dense at 0 deg C than it is at 4 deg C.

Are solids Less dense than liquids?
some solids are more dense than liquids (they sink) but others are less dense which is why not all solids sink
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Are liquids dense?
Some liquids are denser than others. In general, everyday experience, most liquids are denser than gases, but not as dense as solids. There are some exceptions to this rule.
If a substance is viscous is it denser than a less viscous liquid?

Is oil less dense then water?
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Why does cold gases and liquids sink?
Hot air is less dense than the surrounding air and therefore it rises. Cold air, on the other hand, is the opposite. It is more dense than surrounding air and sinks.
Are solids Less dense than liquids?
some solids are more dense than liquids (they sink) but others are less dense which is why not all solids sink
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Is water the least dense than all the liquids?
No. Several liquids, including gasoline, oil and alcohol, are less dense.
Why are liquids usually less dense than a solid of the same substance?
The intermolecular forces are weaker in liquids.
Which cold solid is less dense than the liquid when it melts?
Ice is a solid less dense than the liquid
What phenomenon allows objects or liquids that are less dense to float in liquids that are more dense?
If an object or liquid is is less dense than the liquid in which it floats, that's the reason why it floats, because whatever is less dense floats. If you meant to ask why something MORE dense can float in something LESS dense, one answer is surface tension.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Are gases more dense than liquid?
No. The gas phase is generally less dense than the liquid phase.
Is ice less dense than cold water?
Yes.
Do liquids have high or low density?
Denser than gases but (most often) less dense than solids.
Is warm air less dense than cold air?
yes
