In class today, Dc. Lavelle said that there are three ways to change the energy of a system.
One of the ways was to heat or cool the system and he specifically referred to closed systems.
Can this idea be used on open systems as well?
Or would the added heat be released to the surroundings bc it isn't adiabatic. Thus it would fail as a way to change the E of the system?

Re: Heating/Cooling A System
Because an open system is connected to its surroundings, any heat added would be dispersed throughout its surroundings, so the total E of the system would remain the same. Therefore, it wouldn't work as a way to add energy to a system.

Re: Heating/Cooling A System
I think the only way you can add energy to an open system is by adding or removing the amount of substance.
For example, adding 1 gram of glucose to a system with 9 grams of glucose increases the potential energy.
