Polymers are classified into four groups based on the magnitude of intermolecular forces. They ar —
(i) Elastomers
(ii) Fibers
(iii) Thermoplastic polymers
(iv) Thermosetting polymers
Polythene—Polythene is a thermoplastic polymer.
Bakelite— It is a thermosetting...
Intermolecular forces tend to keep the molecules together but thermal energy of the molecules tends to keep them apart. The three states of matter are the result of the balance...
( a) In the molecules HCl, HBr and HI, dipole-dipole interaction and London forces are present.
(b) The dipole moment of HCl > HBr > HI but boiling point of HCl...
It means that CO2 cannot be liquefied above 30.98o C which is its critical temperature(Tc).
Critical pressure(Pc) – it is the pressure required to liquefy the gas at critical temperature.
Critical volume(...
On increasing the temperature, the kinetic energy of liquid molecules increases so that it can overcome the attractive forces between the molecules and hence liquid can flow more easily i.e....
