Chemical changes involve the formation of new substances and often involve energy changes. In this list, "A piece of paper burns in air with a smoky flame" exemplifies a chemical change, as burning paper results in the production of new substances like ash and gases, alongside energy release. The other options describe physical changes, where the substance itself does not change into something else.

CHEMICAL CHANGE :- A chemical change as the name suggests, brings a change in the chernical composition of the matter. Actually, the substances which are participating in a chemical change have to combine with each other. During this, there is an exchange of their constituents and new substances are formed. This means that chemical changes occur on account of the chemical reactions. A piece of paper burns in air with a smoky flame. This is a example of chemical change because when paper burns a new substance that is ash formed.and from this ash it is not possible to form a piece of paper. But rest of point show temporary change and they easily reversed.

Concept explainers

Polymerization Kinetics

Polymerization is a chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that diverge in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes. Polymerization is generally classified into step-growth and chain polymerization. Polymers are categorized into linear polymer and cross-linked polymers that are produced either by condensation or additional polymerization.
