We do not think it does change.
The proponents of the hydraulic theory for the origin of the state argue that no matter how often energy is conserved or reserved there is a finite amount located in the universe.
work
The only fusion energy in the universe is in the stars like the sun, and there are millions of such stars!
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
heat
I don't really understand the question. But if you are asking "Energy is often measured by the amount of BLANK accomplished." Which I'm assuming you are. So the answer would be "Work"
Heat is the most ubiquitous energy.
If they are astronomers, they classify everything as 'interesting'. I think the answer may be something like "matter or energy". In fact, according to Relativity Theory, mass (of matter) and energy are in many ways equivalent. "Mass-energy" is a term often used to refer to this fact. Pretty well everything in the Universe is matter or energy,
Chemical energy from the batteries are transferred to moving (kinetic) and often sound energy.
Some of the energy will usually be converted into an unusable form of energy, often as heat.
In my universe, radioactive decay involves a change in the nucleus of an atom, often releasing alpha or beta particles, or gamma rays. Sometimes neutrons are released, and occasionally, spontaneous fission occurs.How does it work in your universe?
The SI unit for energy - any type of energy - is the joule. For food, another unit, the calorie, is still often used.
