Question
800 grams of a fuel 'X' is burnt in air whose calorific value is 25 kJ/kg. How much amount ofheat energy will be produced?
Solution
Sure, let's solve this step by step:
Step 1: Convert grams to kilograms Since 1 kg = 1000 grams, 800 grams = 800/1000 = 0.8 kg
Step 2: Use the calorific value to calculate the heat energy The calorific value is the amount of heat energy produced per kilogram of fuel. So, if the calorific value of fuel 'X' is 25 kJ/kg, then 0.8 kg of fuel 'X' will produce 0.8 * 25 = 20 kJ of heat energy.
So, the amount of heat energy produced is 20 kJ.
