#### A cylinder contain 0.45 m^{3} of a gas at 1 x 10^{5} N/m^{2} and 80°C. The gas is compressed to a volume of 0.13 m^{3}, the final pressure being 5 x 10^{5} N/m^{2}. Determine : (i) The mass of gas ; (ii) The value of index ‘n’ for compression ; (iii) The increase in internal energy of the gas ; (iv) The heat received or rejected by the gas during compression. Take, γ = 1.4, R = 294.2 J/kg°C.
