A gas expands adiabatically and its volume triples while its absolute temperature drops 1.55 times. How many degrees of freedom do its molecules have?

Options:

Answer:

Solution:

$3^{γ - 1} = 1.55$ gives $γ - 1 = \frac{ln 1.55}{ln 3} = 0.40$ , so $γ = 1.4$ . With $γ = 1 + \frac{2}{f}$ , $f = 5$ .
