Explanation:

(a) the innermost zone consists of unburnt wax paper given off by the molten wax .

(b) medals on elimination zone in this June party combustion of wax vapour takes place with the libration of a lot of energy the Synergy party decompose the wax vapour into carbon particles.

= calorific

value of work = 18000kj

360000kj

18000kj - kg

1kj = 1/ 18000kg

360000kj = 1/ 18000 × 360000

= 20 kg wood
