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.
