Question
At ordinary temperatures, the molecules of an ideal gas have only translational and rotational kinetic energies. At higher temperatures, they may also have vibrational energy. As a result, at higher temperatures
Options
A.Cv = 3R/2 for monatomic gas
B.Cv > 3R/2 for monoatomic gas
C.Cv < 5R/2 for diatomic gas
D.Cv > 5R/2 for diatomic gas
Solution
On high temperature vibration of atoms is increased so vibrational coordinate will be counted
