Changing Energy of a System

Postby Ting Zheng 3L » Tue Jan 17, 2017 9:47 pm

I am slightly confused on the 3 ways of changing the energy of a system. For heating and cooling the system, does it only work in a closed system?

Hello,

Yes heating and cooling would be only the only way to change energy for a closed system because in a closed system no substance can go in or out, just heat energy can enter and escape. While an open system, because it is open can be changed by substance and by cooling and heating. However, in an open system we pay more attention to the substance. Lastly, a isolated system is well covered and the only way to change the energy is with a piston or allowing the system to do work on the atmosphere.

Hope that helps :)
