Next Question :
Air enters into an engine cylinder at a pressure of $100 \mathrm{kPa}$ and temperature of $300 \mathrm{~K}$ in the suction stroke of an ideal Otto cycle. The cylinder clearance volume is $600 \mathrm{~cm}^{3}$ and compression ratio is $8: 1 .$ The expansion stroke of the cycle is polytropic in nature. The pressure at the beginning of the expansion stroke is $10 \mathrm{MPa}$ and the temperature at the end of the expansion stroke is $1800 \mathrm{~K}$. The polytropic exponent of the expansion stroke is_____________
