Question

1.5 kg of fuel A burns to give 45,000 kJ of energy,
and 4 kg of fuel B burns to give 1,60,000kJ of
energy. Which is a better fuel?​

Answer 1

Answer:

B

Explanation:

Energy by per kg of fuel A =

45000kJ/1.5 kg = 30000kJ/kg

Energy by per kg of fuel B=

160000kJ/4kg = 40000kJ/kg

since the capacity of B is more than A , B is a better fuel
