n: the heat content of fuel. A thermodynamic property, it is the sum of the internal energy of a body and the product of its pressure multiplied by its volume.

n: the internal energy of a substance that is attributed to the internal motion of the molecules. This energy is within the molecules and cannot be utilized for external work.

n: energy possessed by a body by reason of its molecular forces, independent of its potential or kinetic energy. A match or explosive has internal energy.

when a real (not ideal) gas expands, the temperature of the gas drops. During passage of a gas through a choke, the internal energy is transferred to kinetic energy with a corresponding reduction in temperature as velocity increases. The effect for natura
