Question

ScanSolve AI Tutor · Accepted Answer

The question asks to identify the two processes, in sequence, that help in obtaining pure water from salt water when it is heated in a kettle, as shown in the picture.

Analyze the first part of the process.
When salt water is heated in the kettle, the water changes from a liquid to a gas (steam), leaving the salt behind. This process is called evaporation.
Analyze the second part of the process.
The steam then rises and comes into contact with the cooler plate, where it changes back into liquid water droplets. This process is called condensation.
Combine the processes in the correct sequence.
The sequence of processes to obtain pure water from salt water by heating is evaporation followed by condensation.
Compare with the given options.
- A) evaporation and condensation
- B) condensation and evaporation
- C) evaporation and melting
- D) melting and condensation
Option A correctly identifies the sequence of processes.

The correct option is A) evaporation and condensation.
