Answer: Fractional distillation is used to separate liquids with differing boiling points
Explanation:
Sublimation is used to separate volatile substance from a non volatile substance where volatile substance gets converted from solid to gas.
Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.
Chromatography is a separation method where different rates of adsortion of different components is used to separate substances.
The student stirs it because he wants the reaction to take place more quickly.

We need to discuss about reduction of possible environmental damage associated with uranium mining.
There are several extraction processes involved in mining uranium as- (i) surface mining, (ii) heap leaching, (iii) underground mining and so on.
There are so many risks involved towards environment and health.
There are some improvements for long term stabilization of Uranium mining have been documented. They are as follows-back-filling and using residues for the construction of motorways, washing of soil with water, carbon treatment inclusion of new materials like room temperature ceramics for the immobilization of various contaminants, de-watering, and land encapsulation.
