Which among the following purification methods is based on the principle of "Solubility" in two different solvents?

Explain the sublimation technique used for the purification of organic compounds.

By mistake,an alcohol (boiling point $97\,^{\circ}C$) was mixed with a hydrocarbon (boiling point $68\,^{\circ}C$). Suggest a suitable method to separate the two compounds. Explain the reason for your choice.

Which one of the following can be purified by sublimation?

The purification method based on the following physical transformation is $:$
$\text{Solid} (X)$ $\xrightarrow{\text{Heat}} \text{Vapour} (X)$ $\xrightarrow{\text{Cool}} \text{Solid} (X)$

State whether the following statements regarding steam distillation at reduced pressure are True or False:
$i$. It is used in the soap industry.
$ii$. Water pumps,vacuum pumps,or air pumps are used.
$iii$. Liquids with high boiling points do not decompose.
$iv$. The liquid is decomposed.
$v$. The liquid is boiled at a low temperature.
