A 20.0-L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.0 atm. Enough weight is suddenly removed from the piston to lower the external pressure to 1.5 atm. The gas then expands at constant temperature until its pressure is 1.5 atm. Find E, H, q, and w for this change in state.

So this question we have Ah, 20 points. Generally get a bloody move on. I guess so. Volume. Oh, yes. He's trying in the gas for gas continuing. Nicholas Amiga, Ana, a priest in the initial pressure of increased in This is P. Hi. History are mostly and then in love. Way to sort of learn more from the tasting is in a lot of pressure. So finer. What do you want? My five. Mostly. Then the gas expand. That's constant temperature. Job on to do Precious. What? One time? Most. So once you calculate the o. T. E once it calculates dead out to Paige and, uh, q and W or the states so have fourth needs to calculate. Okay, so we gotta use the, uh, the one you want Disgusting creature feature law. So, do you want to collect that? Beat you, but the new one in Sochi one. Okay, say, uh, gas is, of course, that this year will be yours. Envy this year. Got more idea. Okay, a safety. Fine. Nines. Well, we're looking for and this guy's here's a loss to the base, so t wan O p I Mmm. I is across the Pierre be now. So the Queen Ishii's the utmost. Very. I want to fly by 20 points with the jersey. Supposed to she Fine, I won't 0.5. Most fair. What's a fly by? Let's fly by So we have down, uh, dish divided by dish and out me. What's the users? So then we can calculate the walk, don't buy gas and expanding. So this has been to be a negative. Walked on because of gases expanding against the, um, environment against the surrounding. So this appears to be fine on my nose. Really? An issue. Okay. And this sense of you, Pierre said this would be negative. 1.5. I want to live by 40 minus 20 and Mr B, Very little at most. So that's the walked up. And we know that's one litre will share. It's 101.3 job. So 68 leads are betting that most fair, but he wants to. This is negative. Dating. We must do minor stati times 11.3 are the jewels. No, you minus three. He's in all 39. Okay, then we can go ahead, so he you know he is. It wants to kill lost double year. And, uh, that's what he is going to be a zero. Okay, so I need to explain something first. How do we get the outta here? So get outta here. Is, uh, CVT, right? So since the temperature is constant, that makes that doubt t easy, Buster zero. So that the team still posted here that misty after he he was here, he was here. And then, uh, we need to calculate out to hate as well. That's a page ISS cp did see, this is DTC clusters. You know, right here that makes that hate is also lost. 20 So then we can calculate that calculates a queue since we know Q lost. Doubly easy. Good musicals of people stuff you. So we know Walked on. This is walked on w on data. He's here with them plus minus trays. There are +39 jos. So Q would then be cluster 3039 Jos. That's the answer. And this can also be the same teen s 123 That's three lines Yeo for downstairs by three Joes and, uh, Simpson up. Life's today is this could be minus three points. It'll call them stairs, my mr each other
