1. The Gas Laws

   Song by Michael Offut
2. Oh, the gas laws are good to know,
3. You can use ‘em every where you go.
4. We’re talking heavy –duty chemistry,
5. We’re TalkingPV = nRT.
6. The gas laws are just a bunch of facts, To help predict how gases will act.
7. When they’re heated or cooled or squished in a can, The gas laws help you understand.
8. But you need some letters called variables, To describe those gaseous molecules.
9. So let P be pressure and the volume—V, n is the moles and temperature is T.
10. Oh, the gas laws are good to know,
11. You can use ‘em every where you go.
12. We’re talking heavy –duty chemistry,
13. We’re talking PV = nRT.
14. First, let’s talk about P and V, We say they vary inversely. Like a see-saw on the school ground, When one goes up, the other goes down.
15. Now how about that Vand T, We say they vary directly.
16. That’s T measured on the Kelvin scale, Remember that or you might fail!
17. Oh, the gas laws are good to know,
18. You can use ‘em every where you go.
19. We’re talking heavy –duty chemistry,
20. We’re talking PV = nRT.
21. , There are some more laws that we could define
22. But what if we could just combine, Them all together magically. That’s PV= nRT.
23. So remember when you pump up a tire,
24. Hear a log snap or pop in a fire,
25. Watch a big lump of rising dough,
26. The gas laws are good to know.
27. Oh, the gas laws are good to know,
28. You can use ‘em every where you go.
29. We’re talking heavy –duty chemistry,
30. We’re talking PV = nRT.
31. Oh, the gas laws are good to know,
32. You can use ‘em every where you go.
33. We’re talking heavy –duty chemistry,
34. We’re talking PV = nRT.
