Question

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

• A. $1\times {10}^{5}N/m^2$
• B. $1\times {10}^{-5}N/m^2$
• C. $1.4N/m^2$
• D. $1.4\times {10}^{5}N/m^2$

Answer 1

The correct option is D $1.4\times {10}^{5}N/m^2$

The adiabatic bulk modulus of electricity $yp$.

Where y = $\frac{C_P}{C_V}=1.4$ given here,

at NTP, P =${10}^{5}N/m^2$

$\therefore$ Bulk modulus of hydrogen gas = $1.4\times {10}^{5}N/m^2.$
