Question

Problem 4 You draw 10°C water from the tap and pop it into a cubic container to heat for tea. When the cube of 5.6 cm on a side is filled up to the brim you place it in a microwave beam having Eo = 15 kV/m. The water absorbs 75% of the incident energy. How long in seconds) should you microwave the water so it just reaches the boiling point? Make some plausible assumptions about the process to make this problem solvable. List those assumptions in the INTERPRET step and then in DEVELOP step.
