Question

The ratio of the relative rise in pressure for adiabatic compression to that for isothermal compression is :

• A. $\gamma$
• B. $\frac{1}{\gamma }$
• C. $1-\gamma$
• D. $\frac{1}{1-\gamma }$

Answer 1

The correct option is A $\gamma$

For adiabatic case slope of PV graph is given by $\gamma \times \left(P/V\right)$
and for isothermal case it is given by $\left(P/V\right)$.

Ratio of them will be $\gamma$
