Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.

In the 2011 nuclear accident at Fukushima, Japan, an ENV earthquake-triggered tsunami wiped out emergency generators, leaving three reactors without a source of cooling water. Although safety systems shut down the reactors during the earthquake, ra- dioactive decay continued to generate thermal energy at the rate of some 33 MW. In a desperate attempt to cool the reactors, operators used fire engines to pump seawater into the reactors. If 650 m3 of 10°C seawater were injected into a reactor, how long would it take that 33 MW of thermal power to bring the water to the boiling point?
