Question

Why mixture does not have fixed melting and boiling point.Give two reasons

Answer 1

Mixture has more than one constituents which may have same or mostly different properties. So this change leads to change in melting and boiling point.
Also two homogeneous mixture may form a new compound with completely different properties. This leads to the above change.



Hope it works:-):-)
