The total energy and the mass equivalent energy in the universe remain constant. That "total" energy never changes.
You are thinking of the conservation of energy law which states energy can neither ber created or destroyed.
Flashlight = chemical energy(battery) - electrical energy
non spontaneous process happen in the universe but energy has to be provided to them . the free energy change of such processes are positive . the amount of temperature has to be increased to carry out such reactions
The amount of money in a bank account never changes.
there are many types of energy such as kinetic, elastic potential & magnetic but as you should know, energy is never the same, there is an infinite amount of energy in the universe but it never dies, only changes and there isn't necessarily a more powerful energy such as the core of the sun HAS more energy than the core of the earth which would make it more powerful yet this is only because there is more of it in the sun's core. energy would only be more powerful if you increase the ammount there.
Energy is never lost or destroyed.
On the contrary, energy frequently changes from one form to another.
Energy never leaves it just changes form.
The energy called heat, more specifically known as Kinetic Energy - the energy of Heat.Answer2:The energy of motion is cmV = cP, a vector energy. The sum of the particle energy is c x Sum of Pi
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
The sun is the source of all energy except geothermal.
