Q. If $E_{\theta}\ and\ E_{\phi}$ denote the isothermal and adiabatic elasticities respectively of a gas, then $\frac{E_{\theta}}{E_{\phi}}$

A) $< 1$
B) $> 1\ $
C) = 1
D) = 3.2
Explanation

(a) Isothermal elasticity = p, Adiabatic elasticity = $\gamma P$
$\therefore\ \ \frac{E_{\theta}}{E_{\phi}} = \frac{1}{\Upsilon}\ ,\ \Upsilon > 1$
$\therefore\ \ \frac{E_{\theta}}{E_{\phi}} < 1$
