A certain microwave oven delivers 750 watts (J/s) of power to a coffee cup containing 50.0 g of water at 25.0oC. If the wavelength of microwaves in the oven is 9.75 cm, how long does it take, and how many photons must be absorbed, to make the water boil? The specific heat capacity of water is 4.18 JoC-1g-1. Assume that only the water absorbs the energy of the microwaves.
