Why is moving water colder than still water?

Answer 1

This is due to temperature differences. A lower temperature signifies a lower amount of average kinetic energy (as defined by the Maxwell - Boltzmann distribution curve), and therefore cold water molecules slow down, and vice versa, for water molecules at a higher temperature.

Answer 2

For example, water and air at 100°C. Water at 100°C takes in more heat to convert to gaseous state, that is, steam. Since steam takes in heat, it is found to be hotter than water.

Another example: Hot water does not cause as much damage to skin tissues as steam, since steam has a lot of latent heat energy.

Ice takes in a certain amount of heat energy to change to water. Then, water takes in a certain amount of heat energy to change to steam. In this way, steam has more latent heat than other forms of energy, and is found to be hotter than water at the same temperature.

Answer 3

moving water only appears colder to the skin because the water that is closest to your skin is warmed up and stays there when the water doesn't move but with the rushing water it carries away the warmed water thus causes you to rewarm the water in contact with your skin this consumes more energy. Therefore it only feels colder but actually isn't colder at all

Answer 4

Evaporation happens when some molecules that have more energy than others to "unstick" themselves and become a gas. This is why hot water evaporates faster: the molecules have more energy provided by the heat and "unstick" from a liquid state.

Moving water is the same way--the molecules are moving faster due to higher kinetic energy.

Answer 5

water particles in motion have more energy than when stationary. hence they'd have to lose more energy to stabilize into a frozen state.

Answer 6

yes, because water is less dense then air and it slows down the spped of light.

Answer 7

Pure water evaporate faster.

Answer 8

yes
