Question

Method of disposing a substance by heating it to a high temperature in the absence of air

Answer 1

Answer:

Pyrolysis

Explanation:

Pyrolysis is the thermal decomposition of materials at high temperatures in the absence of oxygen.

Pyrolysis relies solely on the elevated heat the materials are subjected to, to alter the chemical composition of the substance being heated.

This method is mostly used in converting molecules in organic material like wood, coal, petroleum to more simpler molecules.

⇒Coke, charcoals,chars and carbon rich compounds are some of the products of pyrolysis.

Examples of pyrolysis:

• Thermal depolymerization
• Cracking
• Dry distillation
• Destructive distillation
