If one mole of a monoatomic gas

\left( {\mathrm{\gamma } = \frac{5}{3}} \right)

is mixed with one mole of a diatomic gas

\left( {\mathrm{\gamma } = \frac{7}{5}} \right)

, the value of

\mathrm{\gamma }

for the mixture is

View answer and explanation

Correct option: B

1.50

Option B (1.50) is correct because it is the value of gamma for the mixture, calculated using the number of moles and individual gammas of the gases.
