Question

Q2-how will you separate the mixture of kerosene and the
more than 25 degree Celsius and they are miscible with each other​

Answer 1

Answer:

The mixture of two miscible liquids such as kerosene and petrol whose boiling points differ by more than 25°C can be easily separated by the technique of simple distillation. The separation is based upon the principle that the boiling point of more volatile (low building liquid of the mixture.

hope it is helps u. plz plz me mark me as the brainiest.

Answer 2

$\blue{\huge{\mid{\underline{\mathcal{Answer :-}}}\mid}}$

A technique known as simple distillation can be used to separate the mixture of miscible liquids, where the difference in boiling point is more than 25°C, to name a few – kerosene and petrol. The whole concept is established on the volatility property of substances. The following are the various steps in the process of simple distillation:

(a) In a distillation flask, take the mixture.

(b) Treat the mixture with heat while a thermometer is affix.

(c) We observe evaporation of petrol as it has a low boiling point.

(d) As the vapours advance towards the condenser, a dip in the temperature causes condensation of the vapours into liquid which can be accumulated in a flask.

(e) We notice that kerosene tends to remain in the flask in a liquid state due to comparatively higher boiling point.

(f) Consequently, the liquids are separated.
