1.	What value of a substance, usually a fuel or food is the amount of heat released during the combustion?(a) Energy value(b) Flash point value(c) Fire point value(d) Auto ignitionThe question was posed to me during an interview.The doubt is from Calorific Value of Fuels in division Steam Power Plant of Energy Engineering
Answer» Right option is (a) Energy value To EXPLAIN: Energy value (heating value or calorific value) of a substance, usually a fuel or FOOD is the amount of heat RELEASED during the COMBUSTION of a specified amount of it. The energy value is characteristic for each substance. It is measured in units of energy PER unit of the substance, usually mass, such as Kj/Kg, KJ/mol, and kcal/kg.
