Question

Will someone please explain what this is asking me? What conclusions can you make about the PV product with Ideal Gas 1, MW = 4 g/mol?

Answer 1

Based off of the portfolio I'm doing there is an inverse relationship between the pressure and volume.

Answer 2

Not really sure I comprehend your question, particularly this part:

What conclusions can you make about the PV product with Ideal Gas 1, MW = 4 g/mol?

what do you mean by Ideal Gas 1

Anyways, I will try to help.

PV = nRT
Where,
P = pressure (atm)
V = volume (L)
n = moles
R = 0.082L*atm/(mol*K)
T = Temperature (K)

Lets see if there really is an inverse relationship between pressure and volume using simple algebra

PV = nRT

P = nRT/V

Seems like there is, assuming moles, Temperature and R are constants.

Pressure is proportional to the inverse of Volume

Answer 3

This makes sense if you think about it higher pressure means that the gas is more condensed (bouncing off the sides of the container more)

Thus as pressure increase volume Decrease
Alternatively,
As volume increases pressure decreases

Answer 4

7.336
1.000 7.336
2.445 3.000 7.335
1.223 6.000 7.338
815.1 9.000 7335.9

Answer 5

Well the first column going downward is Volume & then the second is pressure & the third is PV

Answer 6

I'm not sure what you are asking? Can you please clarify your question.

Know that PV is just Pressure*Volume

Answer 7

The numbers I just gave you are ideal gas 1 so how do I use that to answer the question being asked up above?

Answer 8

It is asking you to look at the data and draw conclusions from it. What does this graph tell you about pressure in relation to volume and vice versa. I just went over it with you :)

Answer 9

That's what doesn't make sense to me I already answered a similar question I'lls how you. :P

Answer 10

Well does the value of PV change much, when the ratio of Volume to Pressure is changed?

Answer 11

I'm so retarded, I was making things seem way harder than they actually were. u_u

Answer 12

I understand what the question is asking me. :P

Answer 13

Don't be so hard on yourself, we are all guilty of over thinking things :)

If you have any other questions feel free to ask me.

Answer 14

But what can I conclude when all of the PV products have no real relation? The first three PV products are 7. something but the last one is 7###. something.

Answer 15

The units of PV are Pressure*Volume or atm*L

Ignore the slight deviations, ultimately PV is a constant

"PV = k1 which means that pressure multiplied by volume gives you a constant, k. This is not the same constant for every reaction; it differs from gas to gas."

Read the portion on Boyle's law

Answer 16

So would that be my answer? I did read a little I'm opening my book right now. xP
Oh, and thank you for helping me!!!! :) <3

Answer 17

You should also comment on the observed deviations in the PV constant, why do you think that there are deviations?

Answer 18

I'm reading about the constant etc. right now. I shoul dhave read my book maybe cakes. xP

Answer 19

What does that mean? :P

Answer 20

What does what mean?

Answer 21

deviations in the PV constant, why do you think that there are deviations?

Answer 22

Sorry tired I should rephrase that,

You should also comment on the observed deviations in the PV constant, why do you think there are deviations in the results?

Answer 23

No need to apologize, what's deviations?

Answer 24

notice how the values of PV are not the same for every result and that they differ, why do you think that they differ?

Remember you are measuring these values in a lab.

Answer 25

It might be good to include a reason for the deviations in PV, if it is a constant shouldn't every value observed be the same?

Answer 26

They differ because of the fact that there are different pressure and volume amounts?

Answer 27

I'm sorry for all of these questions you have been a big help!!! <3

Answer 28

Ahhh nvm I'm tired and not making any sense sorry if I confused you. I just wanted to say that if these values were measured experimentally there could be error inherent in the results which could be a reason for seeing slight differences in PV value

Answer 29

but I dont think that makes any sense so disregard it.

Answer 30

Alright, well thanks for all your help! :)

Answer 31

Yeah No problem if you have any other questions feel free to message me

Answer 32

Thanks. ;)
