Suggest methods for the separation of the following mixtures :
(a) a mixture of liquid A (b.p. 365 K) and liquid B (b.p. 355 K)
(b) a mixture of liquid C (b.p. 348 K) and liquid D (b.p. 478 K).

Explanation

To separate the given mixtures of liquids based on their boiling points, we can use different distillation techniques. Here’s a step-by-step solution for each mixture:

### (a) Mixture of Liquid A (b.p. 365 K) and Liquid B (b.p. 355 K)

1. **Determine the Boiling Point Difference**:
- Calculate the difference in boiling points:
\[
\text{Difference} = 365 \, \text{K} - 355 \, \text{K} = 10 \, \text{K}
