Question

If 2500J of heat is produced by burning 20g of the fuel, then the calorific value is

• A. 125 J/g
• B. 250 J/g
• C. 12.5 J/g
• D. 1.25 J/g

Answer 1

The correct option is A 125 J/g

Heat produced, H = 2500 J

$Mass,m=20gCalorificvalue=\frac{H}{m}=\frac{2500}{20}J/g=125J/g$


Hence, the correct answer is option (a).
