5. Microwave ovens emit microwave radiation that is absorbed by water. The absorbed radiation is converted to heat, which cooks the food. One particular oven emits microwaves with a wavelength of 10.8 cm. How many microwave photons are required to heat 150.0 mL of coffee from 20.0°C to 70.0°C? (q = mcpAT; Cwater = 4.18 J/gºC)
