A) 2500 kg
B) 250 kg
C) 25 kg
D) 2.5 kg
Correct Answer: D
Solution :
1 kg of fuel when burnt gives 20,000 joules of heat energy. 50,000 joules of heat energy will be produced by 2.5 kg of fuel as given below. 1 kg fuel produces \[20\,kJ\,k{{g}^{-1}}\] heat ? fuel produces \[50\,kJ\,k{{g}^{-1}}\] heat \[=\frac{50000}{20000}=2.5\,kg\]You need to login to perform this action.
