Question

Difference between loss of available energy and change in available energy

Answer 1

if we are lossing energy then we will get only less than available enrgy..
suppose available energy is x. then we must get something that is less than x and get (x-something)

but..

if there is being a change in energy then it would be more or less both than available energy
suppose available energy is X then we would get (X+2) or (X-2)
