Homework Statement


On the tv show H2O: Just Add Water, Rikki is a mermaid who has the power to boil water. In the second episode, she boils away all the water in a swimming pool in a matter of seconds. If the average pool contains about 19,000 gallons of water, at roughly 27 degrees Celsius, how much energy did she put out to boil that water away?

If the two atomic bombs dropped on Japan each had an average of 73.5 TJ, how does this compare?

The Attempt at a Solution


This wasn't really homework, I was just watching the show and became curious. But, it sounds like a homework-like question, so I put it here. Any suggestions?

This is a simple heat balance, you must calculate how much energy is needed first to heat up the water to 100 deg C, then to evaporate it.
