### Isolated Systems.

How would you calculate Delta H for an isolated system if q=w=0? Or will it always be 0?
What about for Delta S? If the system doesn't interact with its surroundings, will entropy increase?

the delta U for an isolated system is 0

Delta S should remain zero I think. W depends on what you've got in your system :) unless you've got atoms at abs. zero, W is likely >0

Be sure to not confuse this with the concept of isothermal which means U (internal energy change) is 0. But q and w do not have to be 0.

Your entropy or degeneracy would not change because the isolated system is not interracting with the surroundings in any way.

How does one determine a system is isolated and what does that tell us about its volume and pressure?

Isolated systems cannot exchange heat or matter with the surroundings. They are closed in nature meaning they have constant pressure and volume (unless otherwise stated).
