(a) It is difficult to extinguish a fire on a crude oiltanker, because each liter of crude oil releases 2.80 × 107 J of energy when burned. To illustrate this difficulty, calculate the number of liters of water that must be expended to absorb the energy released by burning 1.00L of crude oil, if the water’s temperature rises from 20.0 °C to 100 °C , it boils, and the resulting steam’s temperature rises to 300 °C at constant pressure. (b) Discuss additional complications caused by the fact thatcrude oil is less dense than water.
