Question
Oxygen, nitrogen and helium gas are kept in three identical adiabatic containers P, Q and R respectively at equal pressure. When the gases are pushed to half their original volumes. (initial temperature is same)
Options
A.The final temperature in the three containers will be the same.
B.The final pressures in the three containers will be the same.
C.The pressure of oxygen and nitrogen will be the same but that of helium will be different.
D.The temperature of oxygen and nitrogen will be the same but that of helium will be different
Solution
ᐃU = 0 (Adiabatic)
U = const
nCvT = const
As O2 and N2 are diatomic, so there temp are equal but is different from He
For adiabatic PVγ = const
For O2, N2 value of γ is same ∴ pressure of O2, N2 remains same but different from He
