A microwave oven heats by radiating food with microwave radiation, which is absorbed by the food and converted to heat. Suppose an oven’s radiation wavelength
is 12.5 cm. A container with 0.250 L of water was placed in the oven, and the
temperature of the water rose from 20.0°C to 100.0°C. How many photons of this
microwave radiation were required? Assume that all the energy from the radiation was
used to raise the temperature of the water.
