The unit for electricity is of course the kilowatt-hour 3.6×106joules ; the unit for gas energy is the therm—the energy required to heat 1000 lb. of water through 100° F., and this is 105 × 106 joules. Thus the therm is approximately 29 kilowatt-hours. In other words, when the...
Kilojoules (kJ) are bigger than joules (J). This is because 1 kilojoule is equal to 1000 joules, so it's like having 1000 of something instead of just 1. What is 1 J of energy? 1 joule of energy is a small amount. It's the energy needed to push or pull something with a force...
Joules are used to measure various forms of energy, including mechanical, thermal, and electromagnetic energy. Calorie (cal) The calorie is a unit of energy traditionally used in the field of nutrition and thermodynamics. It’s defined as the amount of energy required to raise the temperature ...
How many joules of energy are required to preheat a 5.0 kilogram iron skillet from 25.0°C to 150.0°C. The Specific Heat of iron is 0.452 joules/g·°C.Sometimes textbooks or instructors use the following formula to find the energy:q=mcΔT, where "q" is energy in joules; "m" is ...
to create a pot of coffee. Energy can even be measured in joules (pronounced the identical way as ‘ jewels’). One joule is the amount of energy needed to lift 1 pound about 9 inches. It takes 1000 joules to equal a Btu. It might take 2 million joules to create a pot of coffee...

Unit of Energy: The SI unit of energy is Joules and its symbol is {eq}J{/eq}. There are various forms of energy, such as potential energy, kinetic energy, nuclear energy, thermal energy, chemical energy, electrical energy, etc. Regardless of the form o...
So 1 femtojoule = 10-15 joules.The definition of a joule is as follows:The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James ...
