A particular microwave oven delivers 750 watts (exact value). (A watt is a unit of power, which is the joules of energy delivered, or used, per second.) If the oven uses microwave radiation with a wavelength of 12.6 cm, how many photons of this radiation are required to heat 1.00 g of water by 1.00 °C, assuming that all of the photons are absorbed? The specific heat of water is 4.184 J / g•°C at 25°C.

Estimate how many photons of yellow light (? = 559 nm) must be absorbed by 1.0 cm2 of human skin to raise the skin temperature 1.5° C. Assume that the photon energy is absorbed by 1.0 cm3 of tissue. As rough estimates of the tissue's density and specific heat, use the values for water. (The specific heat of water is 4186 J/kg–C°.)
