Among the following the total number of reactions/ processes in which the entropy increases are 1.. 2NaHCO3(s)→ΔNa2CO3(s)+CO2(g)+H2O(g)2. A liquid crystallizes into a solid3. Temperature of crystalline solid is raised from zero K to 100 K4. Hard boiling of an egg5. devitrification of glass6. Stretching of a rubber bond7. desalinization of water8. NH3(g,10atm)→ NH3(g,1atm)

Entropy increases in 1,3,4,81.Chemical or physical processes wherein the no moles of gaseous products increases results into increase in entropy.2. Increase in the temperature results in the exhibition of vibrational degrees of freedom. As a result, entropy increases.3. Devitrification of glass is the process of crystallization of glass from amorphous form to crystalline solids.4. During boiling, denaturation of proteins take place and so entropy increases.
