Q. Value of adiabatic bulk modulus of elasticity of helium at NTP is
A) $1.01 \times 10^{5}\ Nm^{- 2}$
B) $1.01 \times 10^{- 5}\ Nm^{- 2}$
C) $1.69 \times 10^{5}\ Nm^{- 2}$
D) $1.69 \times 10^{- 5}\ Nm^{- 2}$
Explanation
(c) $k_{a} = \gamma p = \left( \frac{5}{3} \right) \times 1.01 \times 10^{5}\ Nm^{- 2}$
$= 1.69 \times 10^{5}\ Nm^{- 2}$
