During crystallisation, formation of crystal can occur in ______________ solution only?
Correct answer: B. Supersaturated
- A. Saturated
- B. Supersaturated
- C. Under-saturated
- D. All A., B. and C.
Explanation
A supersaturated solution has more dissolved solute than equilibrium permits, providing the driving force for nucleation and crystal growth. A saturated solution is at equilibrium, while an undersaturated solution tends to dissolve crystals.

In a laboratory test run, the rate of drying was found to be 0.5 x 10^-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is______________________?
