Because water evapurates
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
The density, freezing point etc. are different compared with pure water.
Adding salt to water lowers its freezing point by an amount that is dependent on the salt concentration. A saturated solution, for instance, will have a freezing point of about -20ºC compared with 0ºC for pure water. In any case, pure water will freeze earlier than salt water, because pure water has a higher freezing point.
Adding salt to water the freezing point decrease.
It is the freezing point of water and equivalent to 32 degrees fahrenheit it is freezing! In Fahrenheit, it is 32 degrees. It is also the freezing point of water in Celsius.
a lower freezing point
The melting point and freezing point of water are physical properties.
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
Salt decreases the freezing point of water and increases the boiling point of water.
The freezing point of water occurs at 273.15 K (at StP)
freezing point means the point water(H20) freezes at.
Water VAPOUR literally does not have a chemical freezing point because it is in the process of evaporation which is above freezing.
