I tried taking hot water to cold water during summer and I felt hot water was better than cold water.

But I am sure they said something along the lines of, if you drink a cold drink the body needs to work to warm the contents of the stomach back up and this expelling of energy made you hotter. That obviously wouldnae explain why a hot drink cooled you down though. But it defo has to be T, coffee doesnae do the same thing, I'm no a big T drinker I prefer coffee, but on a hot day you can't beat a cup of T.

Perhaps you meant cooling. There are lots of simple experiments to do with the rate of cooling of water on the web. Have a closer look using Google and search for "cooling water experiment". Hi Laura

What is “colling” hot water? Perhaps you meant cooling. There are lots of simple experiments to do with the rate of cooling of water on the web. Have a closer look using Google and search for “cooling water experiment”.

It reminded me of how frustrated I would get with the claim that it was faster to make ice cubes with hot water than with cold. Back then, I could only come up with one hypothesis as to why this might seem true--maybe if you put a tray of really hot water in your freezer, it tricks the thermostat to register a higher temperature and thus runs the compressor longer. It is possible that this feedback causes overall temperature to be colder for enough time to make the ice cubes freeze faster. In general, however, I just think the claim is wrong. :) TDL Interesting.
