Question

Sea water freezes at lower temperature than distilled water but boils at higher temperature. Why?

Answer 1

hi mate here is ur answer

sea water freezes at a lower temperature but boils at a higher temperature because of the presence of salt in it

the sea water just boils like fresh water but fresh water is not containing any amount of salt thus it boils at a lower temperature but sea water is containing excessive quantity of salt as compared with fresh water thus it freezes at a lower temperature

hope it helps!!!

please mark as brainliest

Answer 2

Reasons:

• Sea water is composed mostly of salt. (Nacl) Due to presence of impurity of impurities and non volatile solids Boiling point increases and melting point decreases.  
• The number of water molecules free to become freeze decreases due to  the presence of impurities.  
• The freezing point depends upon the attraction between the molecules of the liquid.
• Boiling point depends upon the vapor pressure of the liquid.
• Salt absorbs heat greatly.

Hence, sea water freezes at lower temperature than distilled water but boils at higher temperature.
