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