Don't do that within 24 hours...

 

[UltimateHustla]

24 hours is over lets discuss

 

[hash94]

what was the answer for the last part , about the significance of T?

 

[Sannikutti]

significance of gradient ?
ANy one?
And why do we calculate the gradient
I said to see wether they are proportional or not

And signigicance i said it is 1/nrt,1/constant

 

[ying27kia]

My ans is.
since the graph of 1/v vs p is curve so gradient varied. And it dont verified the boyle's law

 

[Sannikutti]

what was significance of the gradient and why do we calculate it?

 

[Sannikutti]

i mean last page both questions

 

[Sannikutti]

How many marks does each question had?

 

[sadman]

i think the answer was pretty obvious but it was soo obvious that i was scared to write it. I think it was to find the value for the constant!

 

[WhereAmazingHappens]

I messed up 52 hoping between 10/30

 

[angelicsuccubus]

My ans is.
since the graph of 1/v vs p is curve so gradient varied. And it dont verified the boyle's law

1/v vs p was not curved... it was a straight line, but yeh it was a line of best fit so the initial gradient mattered to show the direct proportionality... and the significance was that it was the constant in the boyle's law

 

[Pals_1010]

Significance of the gradient: I wrote that it is the reciprocal of the constant k, 1/k

Why the graph V against P is inappropriate to confirm Boyle's Law: The graph is an exponential curve: we cannot be totally sure if the graph obtained is correct; we will have to calculate gradient at various points to confirm; this is why it is inappropriate

Why we need to calculate the initial slope? Anyone?

I said to it is 1/constant for signeficance
But for why we calculate the gradient i wrote to find the constant of proportionality for narrow range of pressure and volume change

Yeah, I also wrote to confirm the proportionality relationship initially as beyond certain pressure, the gas stops behaving ideally

Is tht rite i think it should be because the question had 2 marks so ya
1 mark for narrow range of pressure and temprature and other one for proportional

 

[Sannikutti]

btw signeficance one was 1 mark rite

 

[Sannikutti]

what abt the graph ?

 

[angelicsuccubus]

what do you guys think the GT would be?

 

[Pals_1010]

yes I think
