Round 1 - Technical 

(2 Questions)

  • Q1. What is Solvent extraction
  • Ans. 

    Solvent extraction is a method used to separate compounds based on their solubility in different solvents.

    • The mixture is then separated into layers, with the compound of interest being extracted into the solvent layer.

    • Common examples include extracting caffeine from coffee beans using water or extracting essent

  • Answered by AI
  • Q2. What is distillation
  • Ans. 

    Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

    • Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

    • The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

    • Common examples of distilla...

Round 2 - Technical 

(2 Questions)

  • Q1. What is evaporation
  • Ans. 

    Evaporation is the process by which a liquid turns into a gas due to heat energy.

    • Evaporation occurs when molecules at the surface of a liquid gain enough energy to escape into the air.

    • It is a cooling process as it removes heat from the liquid.

    • Examples include water evaporating from a puddle on a hot day or sweat evaporating from our skin.

    • Evaporation is an important part of the water cycle.

  • Answered by AI
  • Q2. What is heat transfer
  • Ans. 

    Heat transfer is the process of energy moving from a warmer object to a cooler object.

    • Heat transfer can occur through conduction, convection, or radiation.

    • Conduction is the transfer of heat through direct contact between objects, like a metal spoon heating up in a hot drink.

    • Convection is the transfer of heat through the movement of fluids, like boiling water in a pot.

    • Radiation is the transfer of heat through electromag...

  • Q2. Different between Vaporization and evaporation
  • Ans. 

    Vaporization is the process of turning a liquid into a gas through heat, while evaporation is the process of a liquid turning into a gas at a temperature below its boiling point.

    • Vaporization requires heat to change a liquid into a gas, while evaporation can occur at room temperature.

    • Vaporization is a rapid process, such as boiling water to create steam, while evaporation is a slower process, like a puddle drying up.
