273 degrees kelvin
The equivalent is 273 K.
Kelvin scale assigns the value 0 K (zero kelvins) to absolute zero instead of to the freezing point of water; note that the degree symbol is not used.
Water DOES freeze when potassium nitrate is in it, it just doesn't do so as easily.Any solute will lower the freezing point of a solvent by a characteristic amount; for water it's 1.853 K kg/mol (that's Kelvins, kilograms of water, and moles of solute species; potassium nitrate is ionic and very soluble, so one mole of potassium nitrate will lower the freezing point of a kilogram of water by 3.7 Kelvins).This and similar effects are called "colligative properties", and the simplistic explanation is that the solute disrupts the ice crystal lattice ... essentially, it "gets in the way" of the water freezing.
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.
Salt decreases the freezing point of water and increases the boiling point of water.
273.15 K (Note that the degree sign is not used with the Kelvin temperature scale)
The equivalent is 273 K.
373.15 Kelvins

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.
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.
Because water evapurates
The freezing point of water occurs at 273.15 K (at StP)
