Answer» y consumes 12KG LPG in 30 days .then, the family consumes LPG in a day = 12/30 KG = 0.4 kg .a/c to question, The CALORIFIC value of LPG = 50J/kg you should understand that, calorific value means the MEASUREMENT of heat PRODUCED by specific amount of fuel or food . this is usually expression in joule per kg. so, the average energy consumed per day = calorific value of LPG × amount of LPG consumed in a day = 50 × 0.4 J = 20J hence, 20J energy consumed per day. |
