Lightning strikes can involve currents as high as $25000$ A that last for about $40s.$ If a person is struck by a bolt of lightning with these properties, the current will pass through his body. We shall assume that his mass is $73$ kg $,$ that he is wet $($after all, he is in a rainstorm$)$ and therefore has a resistance of $1\mathrm{.}5,$ and that his body is all water $($which is reasonable for a rough, but plausible, approximation$).$

Part A

By how many degrees Celsius would this lightning bolt increase the temperature of $73$ kg of water?

Express your answer in degrees Celsius.

$T=C$
