chemistry help
    #2133965 - 11/25/03 02:20 AM (13 years, 6 months ago)

This is probably a very simple question, but I've forgotten chemistry. Maybe someone could show me how to solve it.
I'm trying to figure out how many calories it would take to raise 32 ounces of water at 40F to 98.6F. Can anyone help me?

A calorie is the amount of heat necessary to raise 1 gram of water by 1?C. That's actually a little simplified, but not enough different from the full official version to matter much.

Most of your problem is conversion of units. Convert everything to grams and degrees Celsius and the rest is trivial.

32 ounces of water is 946.368 grams.
58.6?F (98.6? - 40?) is 32.556?C.

Heating 946.368 grams of water 32.556?C requires 30809.536 calories.

Happy mushrooming!
