Energy cannot be converted without the loss of usable energy.

The energy of a system approaches a constant value as the temperature approaches absolute zero.

Energy can be converted from one form to another, but it cannot be created or destroyed.

Energy cannot be converted from one form to another without a net gain of usable energy.
