Problem: Suppose that the microwave radiation has a wavelength of 12.4 cm. How many photons are required to heat 215 mL of coffee from 25.0 degree 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.

🤓 Based on our data, we think this question is relevant for Professor Rabinovich's class at UNC.
