(O2) at 25 degrees Celsius, 0.1 MPa are fed into the combustion chamber in the ratio of 0.5 kg O2 to 1 kg hydrazine. The heat transfer from the chamber to the surroundings is 100 kJ per kg hydrazine. Determine the temperature of the products of combustion, assuming that only H2O, H2, and N2 are products.
