Energy in a Ton of Coal

Ever wondered how much energy you could get out of a ton of coal but never had the time to research it? Well if you ever did here's the answer to your pondering On average a ton of coal produces 21 to 22 gigajoules of energy The amount of energy produced by a ton of coal is largely dependent upon the type of coal being burned

How to Calculate the Amount of Heat Released

TL DR (Too Long Didn't Read) To calculate the amount of heat released in a chemical reaction use the equation Q = mc ΔT where Q is the heat energy transferred (in joules) m is the mass of the liquid being heated (in kilograms) c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius) and ΔT is the change in temperature of the liquid (degrees Celsius)
