All ISRO Mechanical & Aerospace papers | ISRO Mechanical & Aerospace 2017

Topic: Thermodynamics

The temperature of the products of combustion when the maximum amount of chemical energy is converted to thermal energy is

  • A. Higher than adiabatic flame temperature
  • B. Lower than adiabatic flame temperature
  • C. Equal to adiabatic flame temperature
  • D. Independent of adiabatic flame temperature

Answer: C. Equal to adiabatic flame temperature

Explanation: The adiabatic flame temperature is the maximum possible temperature achieved for a given fuel and oxidizer, which occurs when the combustion is complete (stoichiometric) and there are no heat losses.
