Here is a new problem that i just tried..
Melting ice in your mouth requires a lot of heat energy, this is why it cools you down. How many calories will your body burn if you melt 6.0 grams of -25.0oC ice in your mouth to body temperature of 37.0oC?
Here is my stab at it....
(1.0 cal/g)(6.0g)(37oC - 0oC) = 2220 cal.
(80 cal/g)(6.0g) = 480
(.5 cal/g)(6.0g)(0oC - -25oC) = 75 cal
Total = 2775 calories needed
The wording of this problem threw me off a bit so i didn't know if it was an exothermic or endothermic process. i think "this is why it cools you down" gives it away though, yes? I think i did it as exothermic.
