Answer 2

Explanation:

a.A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction taking place in a thin zone. Very hot flames are hot enough to have ionized gaseous components of sufficient density to be considered plasma.

b. The substance which vaporizes during burning gives flame. ... Kerosene being more volatile vaporizes completely and gives flame. Charcoal, on the other hand, does not vaporize and so does not produce a flame. Charcoal is a fuel which is used in home and it is combustible substance.
