Call

PV=nRT M.F= `(SF_(4))_(x)`
`(1.02)xx22xx10^(-3)`
`(0.1)/((108)x)xx0.0821xx293`
`x=(0.1xx0.0821xx293)/((108)(1.02)(22.1)xx10^(-3))=1`
M.F. `=SF_(4)`

When 1 mole of an ideal gas at 20 atm pressure and 15 L volume expands such that the final pressure becomes 10 atm and the final volume becomes 60 L.

Correct Answer - D `(P_1V_1)/T_1=(P_2V_2)/T_2` `T_2/T_1=6/3` `DeltaS=2.303xxn{C_p"log"_10T_2/T_1+R"log"_10P_1/P_2}` `DeltaS=2.303xx1{30.96"log"_10 6/3 +R"log"_10 20/10}` `DeltaS=27.22 J.K^(-)1 mol^(-)1`

A sample of oxygen with volume of `500` cc at a pressure of ` 2` atm is compressed to a volume of `400` cc. What pressure is needed to do this if the

Temperature is constant ,so `P_(1) V_(1) = P_(2)V_(2) therefore P_(2) = P_(1)(V_(1))/(V_(2)) = 2[(500)/(400)] = 2.5`atm

`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)`...
