Question

Under what condition is one component system converted to two component systems?

(a) Decrease the temperature

(b) Add a miscible liquid

(c) Add an immiscible liquid

(d) Decrease the pressure

I had been asked this question at a job interview.

My question is based upon One Component System in division Phase Rule of Engineering Chemistry I

Answer 1

Correct option is (b) Add a miscible liquid

For explanation: We know that two immiscible liquids form a heterogeneous mixture. Similarly, if a miscible liquid is added to the one component system, then under high temperature and pressure, it can be converted into two component systems.
