Sorry, Uh, for this problem, it is quite long. So we have Basically we have four processes. The 1st 1 is, uh we have the initial pressure in the initial podium and the 1st 1 is the pressure is constant. Increase the volume, then the voting is constant. Increase the pressure. Next decrease the pressure really nerdy. And the vote him also decrease. Ah, the last step is we, Ah, last episode we decreased level degrees the pressure and to keep the voting constant. So also Ah, the idea guys equations no apply with much accuracy. So anyway, uh, let's look at the people diagram. Firstly, So this is a p misery Initially support. This is the initial point. And the unit for this one's a t m. The unit for the V is a later. So the initial point for P is one. There's the one. Okay. And for B is three. This is three. So for the first step, we increased the volume, but keep the p as constant just whores online, and then we increase the p I. Q b is constant. Uh, what the pressure comes to. Yeah, so then it's just a vertical line going up. Ah, the final state. That at this point, is, uh, you see, it's a 25 So this is a five, and we increased Ah, boarding. And we'll know that we use the pressure, too. Three. So this is a three. This is three. Okay? And then we decrease the volume. And, uh, pressure in Ernie into, uh becomes three. And the pressure becomes too. So this is a business position, too. So it is a straight line, okay? Pointed this direction. And lastly, just go back to the initial state. So this is the PV diagram. And, er, as it's stated in the problem, we not know. Oh, if the idea guess equation, we apply or not. So but the only thing we need to finally just that the next heat blowing into the cycle, right? Ah, So by using the first of them a law, we know that I'm sorry. There is no equal sign here by using the foot of the first of them. All we know, Q. He for the whole cycle, equal to that. You lot stop you. That EU is the changing to the energy for the whole cycle, and the work is the the W's the work done by the gas for the whole cycle because for the whole cycle, that air you better you ihsaa that you should be zero. Because just because the initial point in the bundle point of the same just this point so that a user is zero and cross this out. So basically accuse simply for the w and w the work equal to P T V by definition. And if we do the aim the grow for for the cycle you'll see that this intercourse just represented the area close to buy this lip. Okay, so this is the meaning of this office, integral. So then the probably easy. We just need to calculate the area with the shitty part. Ah, it is It is easy. You just you just need to apply the simple Jeremy Ah, geometric, geometric knowledge. So the area is, uh this is, uh this is the one loss. This is too. In times, this is a two. Do you buy two? And also don't forget that you need to transfer unit into the extent of the unit. So one a t m equal to 1.1 I'm staying to the fifth Posca. One leader is 10 to the negative. Three meters. Cute. Okay, Don't look at you need to do that. So, here. Then. You need thio times, Uh, vectors for the unit for so pressure is one point. 01 times 1 01 10 to 15 and, uh, times another one. Just so this defectors come from come from this, do it just for you. So the final solution should be, uh, 3.3 just 303 I think they're right. So three times. So there. 3.3 Yeah. Three or three kills. So Q is positive. It means that the heat flowing into the gas is positive. So it is means that the net Keats just blow into the guests. That's it.
