Posted by Carson on Tuesday, November 13, 2012 at 10:35pm.

Microwaves are used to heat food in microwave ovens. The microwave radiation is absorbed by moisture in the food. This heats the water, and as the water becomes hot, so does the food. How many photons having a wavelength of 3.00 mm would have to be absorbed by 2.54 g of water to raise its temperature by 1.00 C?
