Question

how does the presence of impurities affect boiling point and freezing point?

Answer 1

impurities are the gangue particles which makes the water thicker which affect its boiling and freezing point.

Answer 2

The presence of impurities may effect in boiling and freezing point in the way that if an impurity is present in a substance that may be kept for boiling or freezing it may change its boiling or freezing point according to the impurities' boiling or freezing point.

for instance if I have to Boil water i should have a heat of 100°C but if an impurity is carried in it, the water may change its boiling point adding the boiling point of the impurity with it. lets say the boiling point of the impurity is 25°C so the boiling point of water may become 125°C.
same is the case in freezing point.
