good try,but water at room temp. has the same density. Unless you boil water and compare,my research shows boiled water has less density.
yeah cold water is denser than room temperature (warm) water.
Hot water is less denser than cold water and has a greater temperature.
Hot water is less denser than cold water and has a greater temperature.
Cold water
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
TEMPERATURE Cold air is denser
Cold.
The reason for this is convection, when the temperature rises the liquid (in this case water) expands, causing it to rise above the cold water which is denser due to the lower temperature. So the hot water rises and the cold water sinks, making a convection current.
its according to what other temperature of water you are comparing it to. water is densest at 4 degrees C so water that is colder then 4 degrees C is technically less dense then water at 4C. in that case the warmer water is denser. but if you mean warm water to be >4C and cold water to be colder then warm water, but not below 4C, then cold water is more dense then warm water. but the question you are probably trying to get answered would have an answer of cold is denser
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
Cold Water. Water expands when it freezes, which makes ice less dense.
