Unlike other kinds of liquids, volatile liquids a. evaporate rapidly at a relatively low temperature. b. freeze readily at a relatively high temperature. c. flow rapidly at a relatively low temperature. d. ignite readily at a relatively low temperature.

Option (A) is the correct answer.

Explanation:

A volatile substance is defined as the one which readily evaporates into its surroundings even at ow temperature.

For example, ethanol is a volatile substance.

Whereas liquids which do not readily convert into vapor state at room temperature or low temperature are known as non-volatile substances.

For example, a sugar solution is a non-volatile substance.

Thus, we can conclude that unlike other kinds of liquids, volatile liquids evaporate rapidly at a relatively low temperature.
