Question

Write true or false. Correct the false statement.

A mixture has a fixed melting or boiling point.

• A. True
• B. False

Answer 1

The correct option is B False

• A mixture is formed when atoms or molecules of the same or different particles combine with each other physically.
• For example - Air is a mixture of gases like Carbon dioxide$\left({\mathrm{CO}}_2\right)$, Nitrogen$\left({\mathrm{N}}_2\right)$, Oxygen$\left({\mathrm{O}}_2\right)$, etc; dust, Water vapors$\left({\mathrm{H}}_2\mathrm{O}\right(\mathrm{g}\left)\right)$.
• The different substances of which the mixture is formed are known as constituents of mixture or components of the mixture.
• Since, there is no chemical bond formation that takes place in the formation of a mixture, every constituent retains its own properties.
• Hence, a mixture can boil at different temperatures.

Hence, the given statement is False.

Correct statement - A mixture does not have a fixed melting or boiling point.
