Answer the following questions and be sure to show all your work. a. It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oilreleases 2.80×10^7 J of energy when burned. To illustrate this difficulty, calculate thenumber of liters of water that must be expended to absorb the energy released byburning 1.00 L of crude oil, if the water has its temperature raised from 20.0ºC to 100ºC,it boils, and the resulting steam is raised to 300ºC.b. Discuss additional complications caused by the fact that crude oil has a smaller densitythan water.
