If 75 g of a fuel produced 2000 J of energy on burning. Then what is its calorific valueA 2600 J/g B 266.67 J/g C 26.67 J/g D 2000 J/g
Question
If 75 g of a fuel produced 2000 J of energy on burning. Then what is its calorific value?
A 2600 J/g
B 266.67 J/g
C 26.67 J/g
D 2000 J/g
Solution
The calorific value of a fuel is the amount of energy produced per gram when the fuel is burned. It is calculated using the formula:
Calorific Value = Total energy produced (J) / Amount of fuel burned (g)
Given in the problem, the total energy produced is 2000 J and the amount of fuel burned is 75 g.
Substituting these values into the formula gives:
Calorific Value = 2000 J / 75 g = 26.67 J/g
So, the calorific value of the fuel is 26.67 J/g. Therefore, the correct answer is C) 26.67 J/g.
