Snigdha filled a large metal bowl with water, and then she put a waterproof electric heater in the bowl. She let the heater heat the water for 15 minutes. By the end of the 15 minutes, the electric heater had used 90 kJ of electric energy, but the thermal energy of the water had only increased by 82 J. Why were these two amounts of energy different?
