Elaborate the statement that physical state of existence at given conditions is a balance between the thermal energy and intermolecular forces.

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: The forces of attractions and repulsion between interacting particles.

(a) noble gases.  (b) between HCl molecules.  (c) Between water molecules or HF molecules.  (d)Between NO3 - and water molecules

( 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...

A will have stronger interparticle forces as it can be liquefied at a higher temperature. 

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....

(a) Both A and R are true and R is the correct explanation of A.

Balance of trade account includes only visible items of trade. It is defined as the difference between export of goods and import of goods. Balance of trade account = exports...

(ii) Low temperature.

(iii) These will form minimum boiling azeotrope. (iv) These will not form ideal solution.
