Which statement describes the law of conservation of energy?

all systems will exchange matter and energy with their surroundings.
all systems can exchange energy, but not matter, with their surroundings.
energy cannot be created nor destroyed, but it changes from one form to another.
energy is destroyed in most chemical reactions when new products are formed.

Answer is: Energy cannot be created nor destroyed, but it changes from one form to another.

The law of conservation of energy states that the total energy of an isolated system remains constant.

For example, coal power plants use coal to heat water into steam, that steam than move a steam turbine, which generate electricity. In this example energy is transformed from thermal to mechanical to electrical energy.

it’s D energy is transferred when atoms are rearranged

Explanation:

That’s the only one that scientifically represents law of conversation of energy

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
