Classification of polymers - Thermoplastics
These are the polymers that can be simply softened repeatedly while heated and hardened when cooled along with little change in their characteristics. The intermolecular forces in these types of polymers are intermediate among those of fibres and elastomers. There is no cross binding among the chain. The softening occurs like the polymer chain go much more and more freely due to not presence of cross link. While heated, they make a fluid which can be moulded into any desired shapes and after that cooled to get the desired product and melt
Q. Show the Structure of sulphuric acid? Theoretical considerations require that the reaction be carried out at low temperature and high pressure. However, at low temperature,
In which region can these properties of the fluid be tuned more simply - near the critical point or at higher pressure/temperature (consider the critical constants and the results

The diffraction of x-ray by a crystal gives 1st order ref at 14•12'' if lattice dist is 3.14 A• wht is the wavelength of x-ray
why the water is compound
Isomers, which vary in the orientation of groups around the double bounded carbon atoms, are known as geometrical Isomers. It is also known as Cis-Trans Isomerism.

The heat of combustion for ethane, C 2 H 6 , is 52.0 kJ/g. How much heat could be released if 1 mol of ethane undergoes full combustion? Answer:
The boron trihalides are highly volatile; BF 3 (b. p., 173 K) and BCI 3 , (b. p., 260.5 K are gases, BBr 3 a volatile liquid (b. p., 319 K) and Bl 3 a low melting solid (m. p.,
