Question

water at Warner temperature cools faster than that at lower temperature.why​

Answer 1

This is a question of heat transfer, and obviously, to make sense, it demands to compare situations where the only thing changing is the water absolute temperature, and with it, its thermophysical properties. Temperature difference with the surroundings or heating media, and the flow situation should be the same.

In general, the answer will depend on how we accomplish the cooling, since relevant water properties will be different. Therefore, this is a good occasion to open a heat transfer manual, learn a little about how to calculate elementary cooling situations, do some little, amusing calculations and find the answer by yourself.

For forced-flow, I have calculated that velocity in W = J/s (or in any other unit of measurement) will be lower at 0+ ºC than at 80 ºC, by a factor larger than two. For other cooling methods, things will be different. In particular, natural flow is very tricky below 4 ºC, where a maximum in density exists. (Above 4 ºC, you can use the elementary handbooks as with any other substance.)

✔Answer:

⭕It all comes down to the way heat escapes and is absorbed by your body. As long as the temperature of the surrounding medium (air or water, most often) is lower than your body temperature, you'll give off heat, and vice versa. The amount of heat your body gives off and how fast it happens depends on how good of a conductor that medium is.
