Suppose an oven's radiation wavelength is 0.125 m. A container with 250.00 g of water was placed in the oven, and the temperature of
the water rose from 20.0°C to 80.0°C. How many photons of this microwave radiation were required to heat the water? (Assume that
all the energy from the radiation was used to raise the temperature of the water.)
