Since the sign is positive, the entropy increased by 88.48 J/K.
Examine the phases of the species present to determine whether a physical or chemical process will cause an increase or decrease in entropy. Keep in mind "Silly Little Goats" to aid you in telling.
[1 Sf K+1 + 1 Sf Br-1 (aq)] ([1Sf(KBr (s))])
[1(102.5) + 1(82.42)] - [1(96.44)] = 88.48 J/K
If the entropy has grown, we say that Delta S is positive, and if it has dropped, we say that Delta S is negative. Due to its ionic nature, KBr is soluble in water and causes the 'K(+)' ions to hydrate.

Answer:
Temperature and Heat Temperature is the measure of the thermal energy of a substance. The hotter an object, the greater the motion of its particles, and the greater the thermal energy. Heat is the transfer or exchange of thermal energy caused by a temperature difference.

Answer: sp hybridization
There are two kinds of polymers : addition polymers and condensation polymers
In case of addition polymers, there is simple addition of unsaturated monomeric units. example: polythene
While in case of condensation polymers, the monomers combine with the elimination of a small molecule like H2O, HCl, NH3 etc.
So here as there is formation of H2O as product there is formation of a polymer and that too a condensation polymer
Example: condensation polymer of diamine and dicarboxylic acid to form a polyamide (Nylon-6,6)
Answer: condensation
formation of polymer
