Question
(a) It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oil releases $2.80\times 10^{7}\textrm{ J}$ 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 1.00 L of crude oil, if the water has its temperature raised from $20.0^\circ\textrm{C}$ to $100^\circ\textrm{C}$ , it boils, and the resulting steam is raised to $300^\circ\textrm{C}$ . (b) Discuss additional complications caused by the fact that crude oil has a smaller density than water.
1. 9.67 L
2. The water will sink below the burning oil, leaving the oil in contact with the air, which it needs to burn. The water can neither smother the fire, nor absorb its heat energy when it is below the surface of the oil.
