Biotic potential is an ecological variable that estimates the maximum number of individuals which an organism, species, community or biome can produce under optimal conditions. It can also be described as a measure of maximum reproductive capacity.

Distilled water does not conduct electricity because it is pure and lacks sufficient ionic concentration, diversity and potential to support any significant flow of electric current.

The law of conservation of matter shows that; matter can be conserved under controlled conditions, thermodynamic differences significantly affect energy systems, matter is constant in a closed system, chemical reactions in closed systems can be accurately predicted, chemical byproducts can be evaluated using reactants and products, mass loss is accompanied by energy loss, natural systems and processes are sustainable.

The difference between heat and thermal energy is in their kinematics; where heat entails energy flow from one body or system to another, while thermal energy causes molecules or components of a body or system to vibrate or rotate about a fixed point.
