basic chem doubt

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.ig use p1v1/t1=p2v2/t2
My approach
Pressure be P and temp be T
Then P/T = 1.004P/T+274
Vol is constant so it can be ignored
but temp changes
Here I take T in kelvin
it will affect volume tho
Yes thats why p1/t1= p2/v2
Closed vessel
Otherwise pressure wouldn't have changed
ig then yes
My answer doesn't match tho
I check online and the solution has T+1 kelvin
But it is 1 deg celsius
,ask T+273=0.004t
,ask T+273=0.004T
,ask T+273=0.004t
wait
U r taking two variables
my keyboard wont let me capitalize
Lol
,ask T+273=1.004T
,ask 68250 -273
67977 degree celsius 💀
250K is the answer
250k hmm
and i got 68250k 💀
wait @hardcoreisdead do p1v1=p2v2 ull get ratio of volume and then try substituting it in p1v1/t1=p2v2/t2
250 Kelvin
That's pointless since volume is constant
(its approximately constant bcuz actual ratio is 1.004)
yes im aware
oh wait im dumb i got it @hardcoreisdead
Isme agar tum ek temp kelvin me le rhe ho to dusre bhi lena pdega dono ya t Celcius me lo ta kelvin me Ans same aarga
@hardcoreisdead i was being so dumb lmfao
it will become 1/T=1.004/T+1
which is ig 1=0.004T which is 250K
i converted 1 in K and one was in C lmfaoooo
That's exactly what I am doing
T in kelvin then T' = T + 274
Cuz 1 deg celsius is 274 Kelvin
1 deg celsius in kelvin is 274 ....?
To initiaal temp bhi t+273 hua na
t consider hi kelvin mein kia hai toh why 273
what happens at such low temperatures? ☠️
oi. it is same dude. change in 1 deg C is same as 1 K
Check this equation. P/T me T is not in celcius
We have assumed T to be in celcius, in which case you will have to put temp on the LHS to be T+273 :)
This is the right realisation :P
also give your doubts prpoper names else you are not gonna be able to find it xD
Name of doubt should ideally have the concept
took me way too long to realise.
i eventually realized if 0 deg celsius is 273K then 1deg celsius is 274 and x deg celsius is just 273+x . i.e increase in deg scale = inc in kelvin scale
issokay :) happens
but good now you will never forget haha
ok sure
yeah fr
