If the heat energy produced by complete combustion of 50 g of fuel is 2750 kJ, then the calorific value
of fuel is
यदि 50 g ईधन के पूर्ण दहन पर उत्पन्न ऊष्मीय ऊर्जा 2750 kJ है, तो ईधन का ऊष्मीय मान है
55000 kJ/kg
55000kJ/g
13750kJ/kg
13750kJ/g​

Answer 1

Answer:

55000kj/kg

Explanation:

Calorific value of a fuel is termed as the amount of energy released by burning 1 kg of fuel in sufficient supply of oxygen.

Here by burning 50 g we get 2570 ok. So by burning 1 kg of fuel we would get 20 times as much energy. So the calorific value of the fuel is 55000kj / kg.
