21w1=Pext(∂V)
w2 = nRT ln(V2/V1)
w3 = nRT ln(V2/V1)
w4=Pext(∂V)
??? it cant b truee...... is it [7]
Explain how you will fidn the work in expanding a gas from
V to 2V
If the process is such that first volume is halved at constantpressure, then doubled at constant temperature. Then halved at constant temperature and then increased 4 times at constant pressure.
Not very tough. Probably very easy :)

1is the ans simply Pext(V) ???
if it is, then i'll post the sol....it seemed 2 b very easy wen i did it using a PV diagram...
24ya has to be PextΔV..................i hope it is not that much tricky..[2]
1wow !! jus see who has come online.......
hello dude how've you been doing lately
24ya Rohan is here..................its such a gr8 thing to see him back here.....[1]
21yah!
actually usin abov 2 formulae twice, me too gettin da same ans!!! PV
24kisi bhi diag par karo.........ans same hi aayega.......maine TV par kiya.[3][3]
1ya...ans same ayega!!![4]
maine TV se nahi kiya..TV bahar waale kamre me chal raha tha!! [3] (i know, bahut bura joke maara hai maine!!)
