Stored Energy Home Experiment CalculationQUESTION: How hot will 2 cups of water get from 2 minutes in a microwave oven?If you know the units of conversion factors, and that anything divided by itself is equal to 1, with a little common sense you can figure out a lot. (If you want more explanation of this technique, here's a simple example of canceling units.) Here are your facts:
Joules Specific Heat of Water = 4180  Kg  Deg. C Power of Microwave = 750 Watts Joule Watt =  Second Weight of Water = 0.454 Kg Time of Heating = 120 Seconds Write an equation so the units cancel and you are left with degrees C. Try it yourself first; here's one way to do it. Here's a more complete explanation! Simple explanation of canceling the Units. Related Pages
