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.
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.
yeah cold water is denser than room temperature (warm) water.
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.
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
Cold.
TEMPERATURE Cold air is denser
Temperature affects the way water moves by changing its density. Cold water is denser than warm water, causing it to sink. This process can drive ocean currents as denser, colder water sinks and displaces warmer, less dense water. Temperature also affects the rate of evaporation and condensation, influencing the water cycle.
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.
The cold dye did not immediately rise into the warm water because of the difference in temperature. Cold liquids are denser than warm liquids, causing the cold dye to stay at the bottom initially. As the dye warms up, it becomes less dense and starts to rise through the warm water.
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.
