In a closed system, neither the energy or matter changes. (Study Island)

Energy transformation is the process that occurs when energy changes from one form to another. A transducer is the device that allows one form of energy to change to another form.
Energy can enter or exist an open system
Whether total energy output is equal to the energy input depends on whether you have an isolated system. It is possible to put more energy into a system than leaves it and vice versa. In that case accumulation of energy in the system can be positive or negative. In general, the formula for the energy balance is: Energy in - Energy out = Change in contained energy (i.e. accumulation). Energy can be added to or removed from a system via work done on (or by) the system, heat added to or removed from the system, and mass added to or removed from the system. Energy can change form in a system or be added or removed from a system via such mechanisms as changes in kinetic energy, changes in potential energy, changes in pressure/volume, phase changes, changes in chemical composition (chemical reactions), etc. In steady state processes, accumulation has to be zero, so any energy input, by any means, must be balanced by energy output.

It helps to think of work as "transfer of energy". If you do energy on a system, its energy content increases. If the system does work on something else, the system's energy content decreases.
the law of conversation if energy is a principle stating that the total energy on an isulated system remains constant regardless of changes within the system
if you add a thermal energy to a system then it will happens nothing because u dont no anything
