`10` litre of a monoatomic ideal gas at `0^(@)C` and `10 atm` pressure is suddenly released to `1 atm` pressure and the gas expands adiabatically agai
Correct Answer - 64 L This is adiabatic irreversible process, so for this process `PV^(gamma)=` Constant, is not applicable `W= -P_(ext)(V_(2)-V_(1))` But for adiabatic process `W=dU=((P_(2)V_(2)-P_(1)V_(1))/(gamma-1))` `PV=nRT " "rArr10xx10=nxx0.082xx273rArrn=4.47` moles `-P_(ext)(V_(2)-V_(1))=((P_(2)V_(2)-P_(1)V_(1))/(gamma-1))...

A sample of certain mas s of an ideal polyatomic gas is expanded against constant pressure of 1 atm adiabatically from volume 2L , pressure 6 atm and
Correct Answer - 6 `W=-P_("ext")(V_(f)-V_(i))` =- (1 atm) (8-2)L =- 6L atm as q=0 so `DeltaE=w " " implies " " 3(8P_(f) -12)=-6` `8P_(f) =12 -(6)/(3)=10 implies P_(f)=(5)/(4) atm` so `(T_(f))/(T_(i))=((5)/(4)xx3)/(6xx2)=(10)/(12)`...

If two gases are taken at same temperature, the density of a gas A is three times that of gas B, while molecular mass of gas B is twice that of A. The
PM=dRT `(PM)/(d)=` constant (for constant T) `(P_(A)M_(A))/(d_(A))=(P_(B)M_(B))/(d_(B))` `(P_(A))/(P_(B))=(d_(A))/(d_(B))xx(M_(B))/(M_(A))=3xx2=6`

Nitrogen gas is filled in a container of volume 2.32 L at 32°C and 4.7 atm pressure. Calculate the number of moles of the gas.
Given : V = 2.32 L, P = 4.7 atm, T = 32°C = 32 + 273.15 K = 305.15 K R = 0.0821 L atm K-1 mol-1 To find : n = number of moles of...
