Photon336 one year ago Question

1. Photon336

#205 a question about the ideal gas law

2. Photon336

ok just posted it

3. Photon336

@Rushwr @Cuanchi

4. Photon336

my first thought was: (if the pressure is lower) then the molecules must be hitting the walls of the container less

5. sweetburger

most likely the is issues created due to the strong intermolecular hydrogen bonding occouring between the gaseous water vapor

6. sweetburger

rip english

7. Photon336

Yeah.. if there's some intermolecular bonding occurring then definitely I think that this would cause the molecules to hit the container less frequently then expected and lower the pressure

8. sweetburger

if the gaseous molecules are being held closer together they will not exert as high of a pressure

9. Photon336

I agree, when i think of pressure i always think of a sealed container

10. Photon336

ill post another one on gases right now

11. Photon336

Got this wrong first time doing it

12. Rushwr

can't it be due to the presence of liquid water?

13. Rushwr

for the 2nd question it is B right?

14. Photon336

I thought it was B as well

15. Photon336

@taramgrant0543664 @sweetburger thoughts?

16. taramgrant0543664

Sorry I went to make a sandwich lol but the second one is B the first one I was also questioning D a little

17. Photon336

I will be back in 30 minutes. will get answers in the mean time !

18. sweetburger

Hmm i think that reads that "the base equation for explanation of defusion of gases"? if so I think the answer should be B. not really sure though...

19. taramgrant0543664

For diffusion I normally use Graham's Law. I know that A is for non-ideal gas B is Boyles Law C is ideal gas law D is kinetic energy looking at each of them the one that seems most like Graham's Law is Boyle's but I am making a lot of random assumptions to say that they would be similar enough

20. sweetburger

A is van der waals right?

21. taramgrant0543664

Yep it is

22. sweetburger

Idk this link might be helpful Im still trying to come up with a clear answer https://www.chem.tamu.edu/class/majors/tutorialnotefiles/graham.htm

23. taramgrant0543664

Maybe it is D then

24. sweetburger

no clue thb. at least well find out when @Photon336 brings back the answer

25. Rushwr

yeah now even I think that it is D

26. taramgrant0543664

Ya for sure but D is making more sense then the other answers now after looking at that link we will find out eventually and hopefully it's not A or C cause that I think would screw us all up lol

27. Rushwr

Wait in which grade are u 2 now? Cuz I actually didn't know that there was a law called graham's law

28. taramgrant0543664

I'm about to go into my third year of university studying chemistry

29. Rushwr

So u learned it there?

30. taramgrant0543664

I knew it before but I really touched on it in my second year physical chemistry class since it is a huge portion of it

31. Rushwr

aaah maybe I will learn it at school after sometime. Chemistry is interesting right?

32. sweetburger

physical chemistry seems very scary

33. taramgrant0543664

Chemistry there is a world of possibilities this coming year take classes from the simple stuff like organic, inorganic and biochem to physical chemistry and that talks about quantum mechanics and then in second semester I will be taking a class called computational quantum chemistry and that's where the fun stuff happens as in I make drugs on computers lol

34. Rushwr

But at school we haven't gone that deep ! But manageable

35. taramgrant0543664

physical chemistry is about thermodynamics both classical and statistical and then it moves onto quantum mechanics its not too bad but it is not easy

36. sweetburger

what level of math did you need to complete?

37. taramgrant0543664

In high school I did advanced functions as well as Calculus/ AP calculus and in university in first year I had to take calculus which is like the AP stuff but a little harder at times and then in second year I had to take differential equations which we studied odes or ordinary differential equations and i'm taking stats this next year for an easy credit

38. sweetburger

hopefully my ap calc goes well for me this year maybe i will have a shot at a chem major then.

39. Rushwr

I am really bad in maths.

40. sweetburger

@taramgrant0543664 do you plan on doing a PhD or are you looking to go to med school or something like that?

41. taramgrant0543664

Chemistry is a great program you really need the math once you get farther into physical chemistry highly recommend paying really good attention to the integral stuff cause if you can only slide by on the basics it gets harder but for the most part if you can derive a formula and put formulas together and plug numbers in its not too bad

42. Rushwr

good that I am not planing on doing chem

43. taramgrant0543664

I'm really not sure to tell you the truth, all I really want to do is be in a lab, the labs at university are so much better than the labs in high school (for the most part) and I absolutely loved the days when all I had where labs and spending 9 hours in the lab was a blast. I'm thinking I will do a masters but I don't know about phd

44. sweetburger

That sounds like it would be very cool/interesting. I like chemistry quite a bit. It's going to be hard to decide on what to major in a year from now. I'll probably chicken out and do biology tbh...

45. taramgrant0543664

Biology is quite fun too I'm doing that as my minor

46. taramgrant0543664

@Rushwr what grade are you in?

47. sweetburger

@taramgrant0543664 thanks for interesting information. Very helpful :).

48. Rushwr

Yeah I'm still schooling my last 2 years

49. taramgrant0543664

No problem feel free to message me if you have any questions about them or bio, they are both fun the labs in both were fun in my opinion I even played around with E. coli in one of my labs they are both good majors that open a lot of doors you can do so much with either of them

50. sweetburger

Alright thanks a bunch :).

51. Rushwr

Thanks alot! @taramgrant0543664

52. taramgrant0543664

You've still got time to learn that stuff you're already really smart @Rushwr and no problem @sweetburger you'll do great in which ever one you pick you're pretty smart too!

53. Rushwr

Thanks alot @taramgrant0543664 U are the only one who says it though. Cuz all my teachers are like u should work more. They always scold me saying that I'm not in the class and blah blah. Thank you again

54. Photon336

Yeah you all are very smart

55. Photon336

By the way I looked at the answer and it'S A

56. sweetburger

Yes agreed

57. taramgrant0543664

@Rushwr you answered that question about decay, I didn't even know where to start (partly because its been three years since I have talked about that stuff) and you answered it like a pro you're doing good keep it up!!

58. taramgrant0543664

A for the second question??

59. Photon336

The second one was D.

60. Photon336

$KE = \frac{ 1 }{ 2 }Mv ^{2}$

61. Rushwr

wait is this the low pressure high temperature ?

62. Photon336

I closed that out and posted the answers for those as well in the other question

63. taramgrant0543664

I was going to say that if the second one was A then I need get back to the books!

64. Photon336

one thing i noticed was that all three were like different versions of the ideal gas law

65. taramgrant0543664

Ya I noticed that too! I'm in the process of making a tutorial on gas laws so they all immediately jumped out and I thought it was a little odd.

66. Photon336

Based on what you guys wrote, you could technically derive grahams law of diffusion from the kinetic energy of the particles
