The answer depends on the units used for the change in mass. Since there are no units, there can be no meaningful answer.
Eequals mcsquared
True
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
The Energy
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
Thr kinetic energy depends on mass and speed:F=0,5 m.v2 (F=ma)
It states that energy can change but mass can not change Chuma.C
It doesn't really have to - there is no such thing as "mass-to-energy conversion", rather, a change in energy will be accompanied by a change in mass. But the change in mass sometimes simplifies calculations.
Binding energy and mass are related. (e = mc2) That is an enormous conversion. It only takes a little mass change to effect a release of a LOT of energy.
The change in potential energy is equal to mass*gravity*change in height
It destroys mass to release energy
No. Energy has an ASSOCIATED mass. There is no such thing as mass-to-energy conversion, or energy-to-mass conversion. In a nuclear reaction, for example, BOTH mass and energy are CONSERVED. For a more detailed explanation, check the Wikipedia article on "binding energy".
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
There is no normal process by which a nucleus can release energy without changing the element. Even gamma radiation, which is photon emission from the nucleus during a restabilization sequence, has a predecessor, i.e. usually beta or alpha, which does change the element.
True
One instance, when a particle is accelerated with sufficient kinetic energy, that energy can change into mass in the form of subatomic particles.
The total amount of mass-energy in a closed system cannot change. Energy can change from one form to another, Mass can change from one form to another, Energy can change to Mass, or Mass can change to Energy; but the total must remain constant. Since Mass and Energy are traditionally measured in different units, we need a units conversion equation to tell us how much of each has changed to the other to get the equations right. Einstein provided us with that from his Special Relativity: E = Mc2
