Question

a family consumes 12 kg of L.P.G in 30 days . calculate the average energy consumed per day if the calorific value of L.P.G is 50kj/kg​

Answer 1

Answer:

20 KJ

Explanation:

The family consumes 12 kg LPG in 30 days

Therefore, in 1 day the LPG consumed = 12/30 kg = 0.4 kg

The calorific value of LPG is 50 KJ/kg

i.e. 1 kg of LPG gives 50 KJ of energy

Therefore, 0.4 kg of LPG will give = 50 × 0.4 KJ of energy

                                                        = 20 KJ of energy

Thus, average energy consumed per day is 20 KJ

Hope this helps.
