(a)
Interpretation:
The short segment of polymer of 3-hydroxybutyric acid (PHB) has to be drawn.
Concept introduction:
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
Two types of polymers:
- Synthetic and biopolymers.
- DNA is an example for biopolymer and these type of polymers are synthesized by cells.
- Polymers synthesized by scientists are called
synthetic polymers and some examples are nylon, polyester etc.
Two types of synthetic polymers:
- Chain-growth
polymers or addition polymers and Step-growthpolymers or Condensation polymers. - Chain growth polymers are formed by the monomer addition to the end of a growing chain.
- Step-growth polymers are formed by combining monomers by removing small molecules of water or alcohol.
(b)
Interpretation:
The short segment of polymer biopol (PHBV) with alternating monomers has to be drawn.

- The velocity distribution function of gas moleculesa) is used to measure their velocity, since the small size of gas molecules means that it cannot be measured in any other wayb) is only used to describe the velocity of particles if their density is very high.c) describes the probability that a gas particle has a velocity in a given interval of velocitiesarrow_forwardExplain why in the representation of a one-dimensional velocity distribution function for a particular gas, the maximum occurs for vi = 0 m/s.arrow_forwardExplain why the representation of a one-dimensional velocity distribution function for a particular gas becomes flatter as the temperature increases.arrow_forward
