Question
n moles of an ideal triatomic linear gas undergoes a proses in which the temperature changes with volume as T = k1V2 where k1 is a constant. Choose incorrect alternative :-
Options
A.At normal temperature Cv = 
R
RB.At any temperature Cp - Cv = R
C.At normal temperature molar heat capacity C = 3R
D.At any temperature molar heat capacity C = 3R
Solution
At normal temperature
Cv =
R = R
At any temperature
Cp - Cv =
R = R
From process T = k1V2
and
Ideal gas equations PV = nRT
We have PV-1 = constant ⇒ x = - 1
⇒ C = Cv +
At normal temperature
C =
= 3R
Cv =
R = RAt any temperature
Cp - Cv =
R = RFrom process T = k1V2
and
Ideal gas equations PV = nRT
We have PV-1 = constant ⇒ x = - 1
⇒ C = Cv +
At normal temperature
C =
