The internal energy of monatomic and diatomic gases are respectively due to
A.
linear motion and rolling motion
B.
rolling motion and linear motion
C.
linear motion and rotatory motion
D.
rotatory motion and linear motion
Answer :
linear motion and rolling motion
Solution :
The internal energy of a monatomic gas is due to linear motion only and that of the diatomic gas is due to rolling (Linear rotatory) motion.
