Q.
In a $p - V$ diagram for an ideal gas (where $p$ is along $y$-axis and $V$ is along $x$-axis), the value of the ratio "slope of adiabatic curve/slope of the isothermal curve" at any point will be (where symbols have their usual meanings).
A) 1
B) 2
C) $C_{p}/C_{v}$
D) $C_{v}/C_{p}$
Explanation
(c) As is known,
$\frac{slope\ of\ adiabatic\ curve}{slope\ of\ isothermal\ curve} = \gamma = \frac{C_{p}}{C_{v}}$
