Question

Describe three ways in which you can change a gas sample.

Madeline Currie · Accepted Answer

this question asks for three ways that we can decrease the volume of a gas. So if we think about the ideal gas equation we&#x27;re looking at the volume of this is what we want to go down. Then there&#x27;s several other factors that we can manipulate here, So are is a constant, so we can&#x27;t change that. But the other three variables that we can change so we want the going to go down, then we could increase the pressure because the pressure goes up and volume goes down, then that will even out this side of the equation and this side will stay constant. We could also decrease the temperature. So if the side of the equation goes down because T goes down than this side of the equation will also go down. So you will go down or we could decrease N and n is the number of moles of gets. So basically we would have to remove some of the gas, and again that would cause this out of the equation to go down. So this side would also go down

three Examples of chemical changes include fire burning, something like a log or a piece of paper. Ah, the stomach acid. Digesting your food for cooking, something like a piece of toast for an egg.

let&#x27;s describe three ways to show the gases exist and these air just three ways that I&#x27;ve come up with. There are others that on can be very plausible. For this. I&#x27;m gonna focus on air, which is a gas. So one way is take a deep breath and breathe out onto your hand. What you feel on your hand is airstrike in your head. The harder you blow, the harder it pushes against your hand. Number two. Holding empty glass upside down, stick it upside down into a basin sink top of pool of water. The reason water doesn&#x27;t fill in the glasses because the empty glasses actually full of air number three. Blow some bubbles underwater or let some air escape the glass and number two above the bubbles air pockets of air surrounded by water. So here you have three ways to show that air, which is a gas, does exist. And this would work for other gases not only just air, and there are also many other ways to show this as well. But here, just three that I&#x27;ve come up with

Okay, So what is the chemical change As a defiant bad burke? A process that that I&#x27;ve also one or more substances change into new substances. It cord chemical change and commonly refers to as a chemical reactions. And there you have full common indicators is color change and temperature change and they&#x27;re crazy. And precipitation percent Tates. Oh, they got some gas produced during the process. Those full Coleman indicators for the chemical reaction. Oh, you could cup chemical change, and it&#x27;ll could find a detailed definition around the page 98 in the book.

Okay, So in a physical change, you&#x27;re substance, Um, is not changed at the particle level or at the molecular level, it&#x27;s still the same stuff. So if we had something like water, we could go from ice toe liquid water to steam. But we still have water, so phase changes would be one example. Um, if you are a visual person like me, you might want to see, So I&#x27;m gonna draw a little particle diagram for you. So water H 20 right has one oxygen and two 100 jin&#x27;s. So in ice, they&#x27;re gonna line up in such a way that the pattern repeats as we, um, draw it. Sorry for my rough sketch there, but it&#x27;s an easy repeating pattern in liquid water. They flow around each other, so not quite as nice of a repeating pattern kind of all over the place. However, they are still tightly packed, but you can see that there is, um, a difference. They&#x27;re not. All of the hydrogen aren&#x27;t in alignment. Um, they don&#x27;t have kind of that nice structure. So we&#x27;ve changed the arrangement of the particles, but they&#x27;re not different particles. Still water and same with steam. in gases. They&#x27;re going to spread out as much as possible, and they might even leave the container if it&#x27;s open. So that would be one example of a physical change. Another example would be something like ripping paper. It&#x27;s still paper, any anything where you were cutting or chopping something. It&#x27;s still that thing at the particle level.

Problem 1 Easy Difficulty

Describe three ways in which you can change a gas sample.

Answer

We can change a gas sample in three ways: first it by heating it, it can dissociate into other gases By freezing the gas,it may loose its properties or by mixing the gas with other gas, we can change the gas sample
