Answer

See the detailed answer below.

Work Step by Step

a) An ideal gas undergoes an adiabatic process from an initial pressure of 1 atm to a final pressure of 10 atm. The gas is diatomic. Find the ratio $V_{\rm max}/V_{\rm min}$. --- b) $$\dfrac{V_1}{V_2}=\left[\dfrac{10}{1}\right]^\frac{1}{1.4}=\bf 5.18$$ This means that $V_1=5.2V_2$ which means that $V_1$ is the maximum volume. Hence, $$\dfrac{V_{\rm max}}{V_{\rm min}}= \color{red}{\bf 5.18}$$
