Table salt (NaCl) melts (or freezes) at 801o C. Salt is difficult to melt because it is an ionic compound. Ionic bonds are the strongest.
Salt lowers the freezing point of water, meaning it needs to be colder for the salt water to freeze compared to pure water. The salt itself does not freeze because its freezing temperature is much lower than that of the salt water solution.
no, because if you put saltwater and freshwater in the freezer saltwater will not freeze completely ,because it has salt in it and it will not freeze at the same rate as freshwater that is my answer to this question.
Water freezes before salt water because adding salt lowers the freezing point of water. This means that salt water needs to reach a lower temperature in order to freeze compared to pure water. As a result, pure water will freeze at a higher temperature than salt water.
The difference is that fresh water will freeze at 0.c and salt will freeze to a lower temperature due to the presence of impurities (salt).
The Great Salt Lake would freeze at a higher temperature than Lake Tahoe because it has a higher salinity level. The salt in the water lowers the freezing point, making it more resistant to freezing than fresh water.
salt
'Faster' is NOT the correct word. Pure water freezes at a higher temperature , than salt water, BUT no FASTER.
Adding salt does not effect the temperature.Answer:Adding salt does not change the temperature at the time you add the salt, but it raises the temperature at which the water will boil
As water freezes salt is released increasing the percentage of salt in the ocean water, the higher the percentage of salt the lower the freezing temperature of the water. The cycle of water freezing -> salt being released -> more water freezing reaches equilibrium at witch point the temperature necessary to freeze more water is lower then the air temperature.
Salt lowers the freezing temperature of water, which means that it has to be colder for the water to freeze.
On the contrary, it takes longer for salt water to freeze - it freezes at a lower temperature than fresh water does.
cos it contains salt :)
