Vedclass · Answer

(D) The adiabatic elasticity $(E_{\phi})$ of a gas is given by the formula $E_{\phi} = \gamma P$,where $\gamma$ is the adiabatic index and $P$ is the pressure of the gas.At $NTP$ (Normal Temperature and Pressure),the pressure $P$ is equal to $1.013 	imes 10^5 \; N/m^2$,which is approximately $1 	imes 10^5 \; N/m^2$.Given $\gamma = 1.4$ and $P = 1 	imes 10^5 \; N/m^2$,we calculate:$E_{\phi} = 1.4 	imes (1 	imes 10^5 \; N/m^2) = 1.4 	imes 10^5 \; N/m^2$.Therefore,the correct option is $(d)$.

The adiabatic elasticity of hydrogen gas $(\gamma = 1.4)$ at $NTP$ is
