Problem: A large container holding 340g of water, initially at 14°C is placed in a microwave oven. The magnetron in the microwave oven can produce 900W of electromagnetic radiation. The microwave is turned on for 3 minutes. Assuming all the microwave energy is absorbed by the water,
Part A: How much water is left in the container?
I need help to solve the above problem and illustrate your calculation.
