Question

heeyy guysss ❣️❣️

Ques ... Nacl solution freezes at lower
temp. than water but boiles at high
termpartue .. why explain?✌️✌️✌️✌️




​

Answer 1

Answer:

hey mate here is ur answer...

it is due to the presence of impurity or effect of impurities in pure water...when non -volatile solids are added eg-nacl to water. boiling point increases and melting point decreases .it is because the no. of water molecules available to become vapourise /freeze decrease due to impurity .so extra heat energy is supplied or extracted to boil it or to freeze it overall increasing boiling point and decreasing melting point.some impurities also decrease the boiling point and increase the melting point.

hope it may help u

and thnxx for this ❣️wonderful question

Answer 2

Ans = When non volatile solids are added eg-nacl to water. Boiling point increases and melting point decreases. It is because the number of water molecules available to become vapourise/freeze decreases due to impurity. As a result, the solution freezes at a lower temperature and boils at a higher temperature.
