A kettle of water has just boiled. At that moment the water inside contains roughly 775 kJ of thermal energy. a) After three hours resting on the counter, the water in the kettle has cooled to room temperature, losing about 170 kJ of thermal energy in the process. Where did that thermal energy go, and by what process(es)? b) Has the quality of the water’s thermal energy increased or decreased? Explain. You have just invented a new light bulb which...
