Consider a pot of boiling water on top of a stove. There is initially a lid on the pot that doesn't let any matter escape from the pot, and the pot is being heated by a flame below. a) Draw a system boundary that contains all the matter in the pot in this initial state. Is this an open or a closed system? Draw any important mass/energy interactions between the system and the surroundings as arrows that indicate the directions of these mass/energy flows. b) Now imagine that the lid of the pot is suddenly lifted and that your system geometry remains the same (i.e., the bounds of your system don't move). Is this an open or a closed system? Draw any important mass/energy interactions between the system and the surroundings as arrows that indicate the directions of these mass/energy flows.
