Interpretation Introduction

Interpretation:

The heat of combustion of polyethylene has to be compared with heat combustion of hydrogen, coal or octane.

Concept Introduction:

Exothermic reaction: Exothermic reactions are those in which evolution of heat takes place during chemical reaction.

Endothermic reaction: Endothermic reactions are chemical reactions in which heat is absorbed during chemical reaction. In such type of reactions, external energy is needed.

Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.

Polymers are macromolecules which are formed a by number of repeating units called monomers.
