Question
The value of the ratio Cp/Cv for hydrogen is 1.67 at 30 K but decreases to 1.4 at 300 K as more degrees of freedom become active. During this rise in temperature,
Options
A.Cp remains constant but Cv increases
B.Cp decreases but Cv increases
C.Both Cp and Cv decrease by the same amount
D.Both Cp and Cv increase by the same amount
Solution
As Cp − Cv = R
For above equation, we can say that both Cp and Cv increase by same amount.
For above equation, we can say that both Cp and Cv increase by same amount.
