Productivity is the measure of efficiency in completing tasks and achieving goals.
Productivity is the ratio of output to input in a given period of time.
It involves maximizing output while minimizing input.
Examples include completing tasks in a timely manner, meeting deadlines, and achieving targets efficiently.
Geothermal gradient affects productivity by influencing the temperature of the subsurface, which can impact the efficiency of geothermal energy extraction.
Geothermal gradient refers to the rate at which temperature increases with depth in the Earth's crust.
A higher geothermal gradient can result in higher temperatures at shallower depths, making geothermal energy extraction more efficient.
Conversely, a lower geoth...

- Q2. How is alumina obtained from bauxite?
- Ans.
Alumina is obtained from bauxite through the Bayer process.
Bauxite is crushed and mixed with sodium hydroxide to form a slurry.
The slurry is heated and pressurized in a digester to dissolve the alumina content.
The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
- Q3. Reaction for Al extraction from alumina.
- Ans.
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
