A cube of water 14 cm on a side is placed in a microwave beam having E0 = 15 kV/m . The microwaves illuminate one face of the cube, and the water absorbs 77 % of the incident energy. How long will it take to raise the water temperature by 44 ∘C? Assume that the water has no heat loss during this time.
