Question

Read the given passage and fill in the blanks by selecting an appropriate option:

When a mixture of two _i_ liquids having a difference of 25°C in their boiling points is to be separated, a _ii_ is used which increases the _iii_ surface area. As a result, when the vapours of both the liquids rise, the _iv_ volatile liquid will condense while the vapours of _v_ volatile liquids will rise.

Answer 2

Answer:

1. Volatile
2. fractional distillation setup
3. total
4. less
5. more

Explanation:

What is fractional distillation?

It is the process of a mixture of two liquids with different boiling points.

The extract with appropriate answers is as follows:
When a mixture of two volatile liquids having a difference of 25°C in their boiling points is to be separated, a fractional distillation setup is used which increases the total surface area. As a result, when the vapours of both the liquids rise, the less volatile liquid will condense while the vapours of more volatile liquids will rise.
