The calorific value of charcoal can be calculated by 6.8 × 10 6 power J / kg

The calorific value of charcoal can be calculated by 6.8 × 10 6 power J / kg


I wonder if you calculate mass according to calorific value, MQ = q, M = 6.8x10 ^ 6 / (3.4 * 10 ^ 7) = 0.5kg = 500g



The calorific value of gasoline is 4.6 × 10 ^ 7J / kg. How many joules of heat can be released by completely burning 210g gasoline


Q=mq=9.66x10^6j
Totally burning 210g gasoline can release 9.66x10 ^ 6 joules of heat
