The total amount of heat produced by a fuel having a calorific value of 20 KJ/Kg 1 was found to be 50,000 joules. How much fuel was burnt ?

Explanation

To find out how much fuel was burnt, we can use the relationship between the calorific value of the fuel and the total heat produced. The calorific value tells us how much heat is produced per kilogram of fuel.

### Step-by-Step Solution:

1. **Understand the Given Information:**
- Calorific value of the fuel = 20 KJ/kg = 20,000 J/kg (since 1 KJ = 1,000 J)
- Total heat produced = 50,000 J
