Consider a gas in a 1.0-L bulb at STP that is connected via a valve to another bulb that is initially evacuated. Answer the following questions about what occurs when the valve between the two bulbs is opened.
-What is true about the value of $\Delta$E?

Question

Quizplus · Accepted Answer

When the valve is opened, the gas expands into the evacuated bulb, and the system reaches a new equilibrium. Since the process is isothermal and the gas expands into a vacuum, there is no change in internal energy (E = 0) because no work is done and no heat is exchanged.
