USE PV=NRT

- anonymous

But i think Charles law is more applicable in it..is'nt it??? @arindameducationusc

- arindameducationusc

YES, P IS CONSTANT

- arindameducationusc

V is proportional to T.
if V is doubled, T is doubled

- anonymous

Then acc to you 150 should be the answer but my teacher told me 423 and i dont know how??

- arindameducationusc

hmmm.....

- arindameducationusc

any units given? like kelvin, Fahrenheit, Celsius?

- anonymous

No....unit is not given so we have to give the answer on the same standard as in the question

- arindameducationusc

hmmm. confusing....

- arindameducationusc

Ya Even @Astrophysics can give a try.

- anonymous

Sure

- IrishBoy123

the answer is 243

Sorry buddy but not understanding why you are adding 273 as we havent been given any unit.???

- IrishBoy123

kelvin

- IrishBoy123

Kelvin is an absolute scale

- IrishBoy123

got it to work yet?

- anonymous

Bro i know all that..but i am just saying that how you knew that 75 degrees in the question is in celsius scale not in kelvin...it can possibly be given in kelvin becoz we havent mentioned any unit in the answer also....... just ''degrees'' not any unit...so it means that we does'nt have to convert 75...

- anonymous

So by keeping 75 how we can get to the answer..??

- IrishBoy123

to get you to the bottom of this, set T to zero in the ideal gas law
see what you get

- anonymous

Bro we have to find T2 and by putting T zero all the equation would be zero....i think the above question is a simple condition of Charles law nothing more thn that and the answer should be 150 according to me but my teacher told me thats not the answer answer is 423 and i was just wandering how the hell this can be the answer and i just supposed if there is a trick behind it so just want you to find that out...please...

- IrishBoy123

really sorry mate, finally gave this the attention it deserves and i totally dig what you say
here we have:
|dw:1442512924916:dw|
so #1
\[\frac{1 \times 1}{75K} = \frac{1 \times 2}{X}\]
\[X = 2(75) = 150K \]
or #2
\[\frac{1 \times 1}{75^oC+273} = \frac{1 \times 2}{X+273}\]
\[X+273 = 2(75+273)\]
\[X = 423K = 150^oC\]
good spot!

Thanks a lot mate...really you are a genius
