Application +4 | -1
An ideal gas has a molar heat capacity C=9R2\mathrm{C}=\frac{9 \mathrm{R}}{2} in the process PT=\mathrm{PT}= constant. Find the degree of freedom of the gas molecule. (R=(\mathrm{R}= ideal gas constant)
View answer and explanation
Correct option: A
5
Option A (5) is correct because the molar heat capacity is related to the degrees of freedom by the equation C = Cv + R/2, and Cv = (f/2)R.
