ANS:C - solubility
Separation of a mixture of two gases by absorption in a liquid solvent depends upon the difference in their solubility.
Here's why:
-
Solubility Difference: When a mixture of gases is brought into contact with a liquid solvent, the degree to which each gas dissolves in the solvent depends on its solubility in that solvent. Gases with higher solubility in the solvent will tend to dissolve more readily than those with lower solubility.
-
Selective Absorption: The solubility difference between the gases determines the extent to which they are absorbed by the solvent. If one gas in the mixture has a significantly higher solubility than the other, it will be preferentially absorbed, leading to separation of the gases.
-
Equilibrium Considerations: During absorption, an equilibrium is established between the concentrations of the gases in the gas phase and their concentrations in the liquid phase. The solubility of each gas determines the equilibrium concentration ratio between the gas phase and the liquid phase, influencing the separation efficiency.
Relative volatility, on the other hand, is a property relevant to distillation processes, where it quantifies the difference in vapor pressures of the components in a mixture. It is not directly related to absorption processes.

ANS:A - Sewage sludge
Among the options provided, the substance that best fits the description of an ideal plastic material is sewage sludge.
Explanation:
-
Ideal Plastic Substance:
- An ideal plastic material exhibits no deformation when stressed up to its yield stress point. This means it behaves like a solid until a critical stress (yield stress) is reached.
-
Behavior Beyond Yield Stress:
- Beyond the yield stress, an ideal plastic material behaves like a Newtonian fluid, meaning its viscosity remains constant regardless of the applied stress. This behavior is characteristic of materials like mud, sewage sludge, or certain types of clay.
-
Options Analysis:
- Sewage sludge: Sewage sludge typically exhibits ideal plastic behavior because it can withstand a certain stress (yield stress) without deforming (like a solid) and then flows like a fluid once this stress threshold is exceeded.
- Rubber latex: Rubber latex is elastic and does not behave like an ideal plastic material.
- Blood: Blood is a non-Newtonian fluid, exhibiting complex viscosity changes under different stresses, not consistent with ideal plastic behavior.
- Sugar solution: Sugar solutions typically behave as Newtonian fluids, with viscosity dependent on temperature and concentration, not exhibiting plastic behavior.
Conclusion:
Therefore, based on the characteristics described (no deformation until yield stress, Newtonian fluid behavior beyond yield stress), sewage sludge is the most appropriate example of an ideal plastic substance among the options provided.
