Suppose an iceberg with a mass of 1.00*10^13 kg is at a uniform temperature of 0.00C. The surrounding ocean has a temperature of 10.0C. A carnot heat engine used ocean water as a heat source and the iceburg as a heat sink. Assuming the waste heat of the engine provides all the heat necessary to melt the iceberg, how much work can this do?
A typical coal burning power plant produces 2000 MW of power. If the carnot engine in this problem was used to generate electricity, how long can the carnot replace a coal burning power plant before the iceberg melts?
