But there are others ways to calculate energy or work. For example, the amount of electrical energy stored a capacitor is given by the expression E = [1/2]CV2, where C is the capacitance in farads and V is the voltage in volts. The result is in joules.

With enough insulation you can in theory boil any amount of water with any amount of energy, given enough time.The key is to supply more energy to the water than it looses.It takes 2260 joules to boil 1 cc of water, joules can be described at watt-seconds.One pint of water is approximately 473 cc, so that will requite 1,068,980 Joules to boil.Given perfect insulation; it would take 17816 seconds / 297 minutes / 5 hours to boil the water with a 60 watt heating element.Assuming that you do not use perfect insulation and given the fact that a peltier element won't give out all 60 watts on the one side, i'd have to say;No you can't boil a pint of water on a 60 watt peltier unit.

Power is joules per second, also known as watts. You can calculate watts if you know volts and amperes by simply multiplying them together, because volts is joules per coulomb and amperes is coulombs per second - multiplying them gives you joules per second. It gets a little complex when you start talking about AC power, because current and voltage is not always in phase, but the principle is the same.AnswerThere is no such thing as 'electric' power. Power is not a 'thing', it's a rate: the rate of doing work, or of heat transfer, expressed (as explained above) in joules per second which has been given the special name, the watt.
To find joules, you have to multiply the force or newtons by distance in meters.
No, to convert from cal. to joules 1 cal. = 4.18400 joules , then 1KCal = (4.18400 *10^-3) joules so 3.25 kcal doesn't equal 3.25 Joules
Various forms of energy can be measured in joules, such as kinetic energy, potential energy, heat energy, and electrical energy. Joules are a unit of measurement for energy and can be used to quantify the amount of energy present in a system or the amount of work done.

To convert Joules to kilocalories, divide the amount of energy in Joules by 4184 (the conversion factor between Joules and kilocalories). Thus, 263 Joules is equivalent to approximately 0.063 kcal.

10 joules per second = 10 watts
4.1868 joules (rounded) amount to one calorie, but here we really have to be careful.That's actually the one called the "small calorie". The food Calorie is capitalized, comprisedof 1,000 small calories, and more properly referred to as the "kilocalorie".The nutritional Calorie is an amount of energy equal to 4186.8 joules.4.1868 joules = 0.001 nutrition Calorie
