A microwave oven using 12.2 cm wavelength radiation is used to heat 297 mL of water. If the water temperature rose from 10.7oC to 100.oC, calculate the number of photons used to heat the water. Assume that all of the microwave energy ends up in the water. Hints: 1. Use the specific heat of water and related...

A microwave oven using 12.2 cm wavelength radiation is used to heat 297 mL of water. If the water temperature rose from 10.7oC to 100.oC, calculate the number of photons used to heat the water. Assume that all of the microwave energy ends up in the water. Hints: 1. Use the specific heat of water and related equations to calculate the amount of energy that was required to heat the water; 2. Calculate the energy that is available in one photon of the microwave radiation; 3. Calculate the number of photons required.
