What kind of calculations can you do with isolated systems?
What kind of calculations can you do with isolated systems? How can you measure a change in anything or calculate the delta u when there is no change in pressure, volume, or energy?
Re: What kind of calculations can you do with isolated systems?
I don't think we'll be doing calculations with isolated systems, at least not in this class. Since isolated systems are classified as systems that don't exchange anything with its surroundings (matter, energy, etc.), maybe a change in energy will happen within the isolated system itself, although I'm not sure how feasible that would be without any input from its surroundings.
Re: What kind of calculations can you do with isolated systems?
If a system is isolated, then by definition, the internal energy cannot be changed due to an exchange of heat or work. dU would always be zero because the system's mass-energy cannot change.
Re: What kind of calculations can you do with isolated systems?
Delta U would remain 0 because there is no exchange of energy in an isolated system. I also believe we won't be doing any calculations.

You are right, in an isolated system there won't be any change in deltaU because it is isolated, meaning no heat or work will be done on the system. Nothing will change, and even if years go by, the internal energy of an isolated system will stay the same.

Hello!
I do not think we will be doing any calculations with isolated systems. However, you should keep in mind that ∆U = 0 for all isolated systems. This is because, ∆U = q + w. There is no heat transfer or work being done by an isolated system. Therefore, the isolated system's change in internal energy will always be zero.
Hope that helped!

Hi! As others have mentioned above, I do not think we will be doing calculations with isolated systems in this class . Isolated systems don't exchange anything with the surroundings, its total mass and energy remains constant, so its delta U will be zero.
