1.	The minimum temperature at which a substance begins to burn is called ________(a) Fire point temperature(b) Auto ignition(c) Ignition temperature(d) Flash point temperatureThis question was posed to me in examination.The origin of the question is Combustion of Fuels in chapter Steam Power Plant of Energy Engineering
Answer» Correct answer is (c) Ignition temperature The explanation: The minimum temperature at which a substance begins to burn is called ignition temperature. No substance can catch FIRE unless it is HEATED up to a certain minimum temperature. The ignition of EVERY substance is definite. For example, the ignition temperature of white phosphorous is 35°C. It MEANS, white phosphorous STARTS burning only if it is heated up to 35°C.
