0.2 mole of a diatomic gas at $2 7^{\circ}$ C expands isothermally to double its volume and then adiabatically to double it again ( $γ = 1.4$ ). Find the final temperature in °C (one decimal).

Answer:

-45.60

Solution:

$T_{f} = 300 \times 2^{- 0.4} = 227.4$ K = $- 45.6^{\circ}$ C. (The adiabatic work is $n C_{v} Δ T = 302$ J.)
