A cube of ice water (11 cm a side at -15 oC), is placed in a microwave with a beam having E0 = 27.47 kV/melectric field. The microwaves come from one side and will illuminate one side of the cube. The water absorbs theenergy at roughly 82% efficiency. How long will it take to raise the ice water's temperature to room temperature (20oC). Assume that the ice doesn’t exchange heat with the environment during this time.
