vocabulary for the weak:
enthalpy, the measure of the energy content of a system in relation to it's mass.
The definition can mislead in that big and heavy doesn't necessarily have more energy unless you render it. lol

entropy: 1, a thermodynamic measure of the amount of energy unavailable for useful work in a system undergoing change.
2, a measure of the degree of disorder in a substance or system: entropy always increases and available energy always diminishes in a closed system, the universe for example.

3, in information theory, the measure of the information content of a message vs the veracity of the source.

Obviously both terms have political currency. lol
