• # question_answer The adiabatic elasticity of hydrogen gas $(\gamma =1.4)$ at NTP is A) $1\times {{10}^{5}}\ N/{{m}^{2}}$   B) $1\times {{10}^{-8}}\ N/m2$ C) $1.4\ N/{{m}^{2}}$ D) $1.4\times {{10}^{5}}N/{{m}^{2}}$

[d]${{E}_{\varphi }}=\gamma P=1.4\times (1\times {{10}^{5}})=1.4\times {{10}^{5}}N/{{m}^{2}}$
