How much energy, in joules, does it take to raise a gallon of room temperature water, ~21.1°C, to boiling? Some useful values: kg gal Pwater = 3.79- J g°C Cw=4.18- 4. Consider the gallon of water from the scenario in the previous question. If we use a 600 square centimeter magnifying glass to focus the sun's light on the water, how long will it take to raise the water to boiling? Ignore any heat lost by the water during the process. Some useful values: The radiant power of the sun at noon on the Earth's equator is about 1,370 watts per square meter. That is 1,370 joules of energy every second over every square meter of the Earth near the equator.
