Applying : ${(n_{1} + n_{2})}_{i n i t i a l} = {(n_{1} + n_{2})}_{f i n a l}$

Assuming the system attains a final temperature of T (Such that 300 < T < 60)

(Heat lost by N₂ of container l) = (Heat gained by N₂ of container II)

$n_{1} C m (300 - T) = n_{2} C m (T - 60)$

$(\frac{2.8}{28}) (300 - T) = \frac{0.2}{28} (T - 60)$

14 (300 – T) = T – 60

$P = (\frac{3}{28}) \times 8.31 \times \frac{284}{3 \times 1 0^{- 3}} \times 1 0^{- 5} b a r = 0.84287 b a r$

$P = 84.28 \times 1 0^{- 2} b a r$

$\approx 84 \times 1 0^{- 2} b a r$
