In the course reader, there are three ways of changing the energy of a system, but they only apply to closed or open systems. How does one change the energy of an isolated system?

You cannot change the energy of an isolated system, as stated in the first law of thermodynamics. This law states that the internal energy of an isolated system is constant. For example, the universe is an isolated system, therefore its energy is constant.
