As humans age, it is known that their energy (kcal) intake decreases.

But at a million miles, it is completely obscure, because radiant energy decreases according to the fourth power of the radius.

In other words, when a spontaneous reaction occurs at constant temperature and pressure, the free energy of the system decreases.

The free energy of any substance decreases with increasing temperature.

If no heat enters the gas, the energy in the gas molecules is decreasing by the same amount.

This means the kinetic energy of the fluid is decreasing.

Now as the internal energy has decreased so has the temperature.

As a system undergoes changes, its free energy will decrease.

As an object moves in the direction that the force accelerates it, its potential energy decreases.

Unserved energy decreased to 11% of the potential demand in 2002, down from 40% in 1991.
