When 1 mole of CO 2 ( g ) occupying volume 10 L at 2 7 ∘ C is expanded under adiabatic condition, temperature falls to 150 K . Hence,final volume is

In adiabatic expansion T 1 T 2 = ( V 2 V 1 ) γ − 1 for CO 2 (triatomic gas) is, ∴ ( 300 150 ) = ( V 2 10 ) 0.33 ( 2 1 ) = ( V 2 10 ) 0.33 ( 2 1 ) 3 = V 2 10 8 1 = V 2 10 V 2 = 80 L

When 1 mole of $CO_{2} (g)$ occupying volume $10 L$ at $2 7^{\circ} C$ is expanded under adiabatic condition, temperature falls to $150 K$ . Hence,final volume is

Options:

Answer:

Solution:

In adiabatic expansion $\frac{T _{2}}{T _{1}} = (\frac{V _{1}}{V _{2}})^{γ - 1}$ for $CO_{2}$ (triatomic gas) is, $∴ (\frac{150}{300}) = (\frac{10}{V _{2}})^{0.33} (\frac{1}{2}) = (\frac{10}{V _{2}})^{0.33} (\frac{1}{2})^{3} = \frac{10}{V _{2}} \frac{1}{8} = \frac{10}{V _{2}} V_{2} = 80 L$
