from a person's skin when 175 g of isopropyl
alcohol evaporates? How many kilojoules?
B)How many kg of water would this

(B) calc the # of grams of water that can be cooled at freezing by melting the ice cube?

Answer 1

There are a few was sp change the degee of body temp to go higher, put a bar of soup uner your armpit, another one is to hold the themotitor to a lamp shade, or wrape it up in a heating pad for no more miniutes in a glass of water for no more then 3 minute, make sure you put it into a mirco soft safe cup.

as for lowering a temp, put the subjct into a luke wark bath and about 1/3 cup of acholol, you can also put them is a bath of ice or run cold cater in their wrists and cold comprest on the back of he nec.
