if we have same tempature water and air, why does the water feel colder to the air when we go for a swim for example?
In: Other
temperature and heat are not the same thing
heat your oven to 400 degrees and put a sheet of tin foil and a ceramic casserole dish in it
wait 30 minutes and take out the foil with your bare hands. Toasty, maybe burns a little bit, but just little bit.
then grab the casserole dish with both hands. After you get back from the ER and clean up the broken dish you dropped because it WAS SO DAMN HOT, consider:
both items were 400 degrees. But the tinfoil was thin and did not have much mass so it did not contain that much heat energy. The casserole dish is ceramic is dense and heavy and can contain a lot more heat energy
likewise water is denser than air and can contain more heat energy at the same temperature
conversely, water can also absorb a lot more heat energy than air at the same temperature
