1. Assuming 4,686,400,000 MWh of energy was “dumped” into lake Erie instantaneously, what would be the increase in the water temperature of the lake

2. Assuming all of that energy was dumped to the earth’s atmosphere instantaneously. How thick (i.e. altitude-wise) would the atmosphere have to be in order to have a temperature rise of no more than 0.5 C? Assume the entire atmosphere is at 15 C and 101.33 kPa. Assume constant specific heats at 300 K & neglect any boundary work.
