Air pollutants produced by mining activities, and their characteristics

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
