\(\mathrm{TV} ^{\gamma-1}=\mathrm{C}\)
\(300 \times \mathrm{V}^{\frac{7}{5}-1}=\mathrm{T}_{2}\left(\frac{\mathrm{V}}{16}\right)^{\frac{7}{5}-1}\)
\(300 \times 2^{4 \times \frac{2}{5}}=\mathrm{T}_{2}\)
Isobaric process
\(\mathrm{V}=\frac{\mathrm{nRT}}{\mathrm{P}}\)
\(\mathrm{V}_{2}=\mathrm{kT}_{2}\)
\(2 \mathrm{V}_{2}=\mathrm{KT}_{\mathrm{f}}\)
\(\frac{1}{2}=\frac{\mathrm{T}_{2}}{\mathrm{T}_{\mathrm{f}}} \Rightarrow \mathrm{T}_{\mathrm{f}}=2 \mathrm{T}_{2}\)
\(\mathrm{T}_{\mathrm{f}}=2 \times 300 \times 2^{\frac{8}{5}}=1818.85\)
