Statement 1: Charcoal is a better biomass than wood.
Statement 2: Charcoal burns without flames; is comparatively smokeless and has higher heat generation.
Statement 1 and statement 2 are correct, statement 2 is the reason for statement 1.
Charcoal is produced by burning plant or animal substance in the absences of oxygen. All the volatile substances including water are already evaporated from charcoal. It is a better biomass than wood as it burns without flames; is comparatively smokeless and has higher heat generation than wood.
