Suppose that the microwave radiation has a wavelength of 12 cmcm . How many photons are required to heat 265 mLmL of coffee from 25.0 âCâC to 62.0 âCâC?  Assume that the coffee has the same density, 0.997 g/mLg/mL , and specific heat capacity, 4.184 J/(gâ K)J/(gâ K) , as water over this temperature range.
