How many joules is a kg of wood?
A common hardwood, red oak, has an energy content (heat value) of 14.9 megajoules per kilogram (6,388 BTU per pound), and 10.4 megajoules recoverable if burned at 70% efficiency.
How many joules is a pound of coal?
4.11E6 Joules
“Using an efficiency of 30% for transforming the heat energy of the coal into electrical energy and transmitting it to your light bulb (probably optimistic), we see that one pound of coal provides 4.11E6 Joules to your light bulb (I take 13,000 BTU/lb x 0.3 efficiency × 1054 Joules/cal) [sic.

How much energy is released when 1 kg of coal is burned?
With a complete combustion or fission , approx. 8 kWh of heat can be generated from 1 kg of coal, approx.
How many kWh are in a kilo of coal?
8.141 kWh
1 kg coal equivalent corresponds to a value specified as 7,000 kilocalories (7,000 kcal ~ 29.3 MJ ~ 8.141 kWh) and thus approximately the calorific value of hard coal which, depending on the type, amounts to between 29.3 MJ/kg (gas-flame coal) and 33.5 MJ/kg (anthracite).
How many joules are in a gas?
To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules. Therefore, a liter of gasoline has 8.76 kW/hr of energy in it, which is a much more manageable number.
What are joules in physics?
joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
