How Is Energy Conserved Within a Closed System?
Answer:
Closed system means only energy can transfer from one system to another but mass cannot transfer.
Law of conservation of energy is the total energy is remain constant it changes from one form to another.
For example, our earth is closed system, it takes energy from sun in the form heat energy without exchanging of mass. Energy may be potential, kinetic, heat or internal energy
But in the earth, this heat energy takes by plants or trees, produces coal to create electric energy.
Also in the earth water energy converts from potential energy into kinetic energy in nozzle and produce electric energy.
It means, within Closed system, energy is conserved
is energy conserved
