C V =( fR /2), degree of freedom for diatomic gas and polyatomic gas at room temperature is f but at higher temperature their degree of freedom increases by one due to vibrational motion of molecule

Q. At ordinary temperature, the molecules of an ideal gas have only translational and rotational kinetic energies. At high temperature they may also have vibrational energy as a result of this at high temperature

$C_{V} < \frac{3 R}{2},$ monoatomic

$C_{V} = \frac{3 R}{2},$ monoatomic

$C_{V} < \frac{5 R}{2},$ diatomic

$C_{V} = \frac{5 R}{0},$ diatomic

$C_{V} = \frac{f R}{2},$ degree of freedom for diatomic gas and polyatomic gas at room temperature is $f$ but at higher temperature their degree of freedom increases by one due to vibrational motion of molecule

CV​<23R​, monoatomic

CV​=23R​, monoatomic

CV​<25R​, diatomic

CV​=05R​, diatomic

CV​=2fR​, degree of freedom for diatomic gas and polyatomic gas at room temperature is f but at higher temperature their degree of freedom increases by one due to vibrational motion of molecule
