I just want to make sure my logic is correct.
Hot coffee in a vacuum flask (thermos) is an example of what type of sytem?
Choices:
Closed
Open
Isolated
I thought it was closed system because the coffee is not interacting with the surroundings. But one of my classmates said he thought it was open because it's interacting with the flask. So which one of is correct?
Edit: I know believe it's isolated because heat is not exchanged. at least I don't think it is
