Suppose that the microwave radiation has a wavelength of 12.4 cm . How many photons are required to heat 285 mL of coffee from 25.0 ∘C to 62.0 ∘C? Assume that the coffee has the same density, 0.997 g/mL , and specific heat capacity, 4.184 J/(g⋅K) , as water over this temperature range.
Express the number of photons numerically.
