Problem 101

Consider a system consisting of the following apparatus, in which gas is confined in one flask and there is a vacuum in the other flask. The flasks are separated by a valve. Assume that the flasks are perfectly insulated and will not allow the flow of heat into or out of the flasks to the surroundings. When the valve is opened, gas flows from the filled flask to the evacuated one. (a) Is work performed during the expansion of the gas? (b) Why or why not? (c) Can you determine the value of $\Delta E$ for the process?

and this's a system we can often tease. This is a single entity is his sister. It's the problem of this. Is there in the form of a P A. That's creepy, right? So and this We have assumed that this plus properly, it's better. We're not allowed to floor it in tow out of the class. So no change in temperature every out of the plastic. But it's Randy when in fact it's often they can flow from the field from a Toby if they work performed during the expansion of the cast. So this is not work, but what it cost O. P came in for, You know, the totem holding in the challenge is three plus a peepee. Finally, finally, in the cabin is president plus every business stratosphere. So that is the mission. Let's sit out for off the gas a day. But some of them are staying, so the following will still be the same. I'm still the same. So you if you don't let that that we have fire by mail of gas, Okay, I'm just using them a zero. And be totally is five. If I have five like three of them, like some flowing tto be three minutes to ask flow into the It's time for Mr Fire So that's not changing for you. So there's no walked on. So what will be in rescuing all the pressure going to be times here. So work zero. No work. So because no problem romantic things, so be it Now coming to me for a beaker kid knows you. I came. This is age because this is serious. His one is ever see Jinyan creature So it depends on the temperature. Once we know the mass of the castle nor the following can open our mouths off campus. So especially the part about changing their preacher. If there's an actual live creature, there will be ableto copulating tonight Tonight, when there is no change in their return Tonight and I just can't be here. You guys know changing creature change and temperature
