Problem 2.81

The volume of gas consisting of rigid diatomic molecules was increased η=2.0\eta=2.0 times in a polytropic process with the molar heat capacity C=RC=R. How many times will the rate of collisions of molecules against a vessel's wall be reduced as a result of this process?\operatorname{cess} ?

Reveal Answer
 Decreases η(i1)/(i2)=2.5 times. \text { Decreases } \eta^{(i-1) /(i-2)}=2.5 \text { times. }
