Question

The ratio of the adiabatic to isothermal elasticities of a triatomic gas is

• A. $\frac { 3 } { 4 }$
• B. $\frac { 4 } { 3 }$
• C. 1
• D. $\frac { 5 } { 3 }$

Answer 1

Answer: (B)

$\frac { 4 } { 3 }$

Answer 2

For triatomic gas $\gamma = 4 / 3$ $\therefore$Ratio of adiabatic to isothermal elasticity $\gamma = \frac { 4 } { 3 }$.
