Suppose that the microwave radiation has a wavelength of 12 . How many photons are required to heat 275 of coffee from 25.0 to 62.0 ? Assume that the coffee has the same density, 0.997 , and specific heat capacity, 4.184 , as water over this temperature range. Express the number of photons numerically.
