Hi there in problem number two. We have some gas in a movable piston. So this part right here is movable. It can slide up or down and our gas is here in the piston. So, we have three different scenarios here that they would like us to describe what is going to happen in each of these scenarios. And we need to redraw this for each of these scenarios. So let her a let me draw the container. Mhm. Okay. In letter A. It says the pressure is remaining constant, But the temperature of the gas is being increased from 300 to 500 Kelvin. So when temperature goes up and pressure remains constant, the volume is directly proportional. It will increase By the same proportion. So going from 300 to 500 is not quite doubling. So, if our original piston was here, our new piston height is probably right about up here. Make that center longer. All right. And we have our gas particles in there because they have heated up. They are moving faster. They have more kinetic energy and they will cause an expansion in the container. All right, moving on to letter B, drawing our container. Now the temperature remains constant and be but the external pressure on the piste and has increased From 101.32 to 2.7 while temperatures constant. So in other words, the pressure, the outside atmospheric pressure has approximately doubled, so pressure and volume of a gas sample are inversely proportional. If pressure increases and by doubling the pressure or the volume is going to be cut in half. So that means the piston will get pushed further down. I just cut the original volume in half. Or tried to anyway. And we still have our gas particles in here, Right? And then finally let her see same gas sample in that same container. But now The temperature is decreasing from 300 to 200 while the pressure remains constant. So temperatures decreasing. The original piston was right about here, Going from 300 to 200, so it's going down by a third. So if the temperature decreases by 1/3, The volume will decrease by 1/3. So that was my attempt to show the volume of the container At 2/3 what it was originally. So this is approximately what these pistons will look like after each of these scenarios.
