In a burner 1 kg/s methane is combusted with 20 kg/s air. both gases are introduced into the burner at 25 Celsius and 1 bar. it may be assumed that the air is 21% oxygen and 79% nitrogen on a molar basis that all components behave as ideal gases and that no heat is lost to the surroundings.

1. How much heat in kW will be released?


2. Find the temperature of exhaust gases leaving the burner in the previous part
