Rubber bands comprise of loosely packed chains of atoms.When stretched, the chain of atoms get neatly lined up in rows and hens the entrops of system decreases whereas when contacted the chains get tangled up in a mess increasing entropy of system. Also on strectching rubber band, it is observed that any substance brought in its contact gets heated up. Based on this information, answer the following questions. Which of the following statement(s) is/are correct?

Answer» A van dar wallls' get at is CRITICAL condition SUBJECTED to adiabatic free expansion experiences cooling effect. If for a reaction `DeltaH_(400)^(@)K=DeltaH_(200)^(@)K then DeltaS_(300)^(@)K` should be EQUAL to `DeltaS_(500)^(@)K`. The value of compressibility FACTOR of a real gas is 1 at Boyle's temperature for all range of pressures. Ametal peroxide has 68% by mass metal, hence equivalent mass of its chloride will be 69.5 gms. Answer :a,b,d
