Isolated Systems

Why must the energy of an isolated system remain constant?

That's because no heat nor any matter is being lost or added to the system. This is described the law of conservation of energy, which states that the total energy of an isolated system is constant. Although energy can change forms, an example being mechanical to thermal, it can't be created nor destroyed.

In an isolated system, nothing is exchanged between the system and the surroundings. So nothing gets in and nothing gets out, including matter and energy. If energy can't get in or out, that means it stays constant.
