It does not very significantly because melting does not involve gas-phases molecules. Boiling, on the other hand, is strongly affected.

What affects freezing point?

The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.


What information does the water freezing point pressure chart provide?

The water freezing point pressure chart provides data on the relationship between pressure and the temperature at which water freezes. It shows how the freezing point of water changes as pressure increases or decreases.


How does salt affect the melting and freezing point of water?

Salt decreases the freezing point of water and increases the boiling point of water.


Explain why the water froze at a temperature lower than 0 degrees Celsius ?

Pure water, at normal atmospheric pressure freezes at 0 deg C. If the pressure is greater than normal atmospheric pressure (760mm of Hg) or if the water contains dissolved substances, its freezing point will be below 0 deg C.


What is the effect of decreased pressure on boiling point and freezing point of water?

Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.


How does adding salt to water affect the temperature?

It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.


How do altitude affect freezing melting and boiling points of water?

As altitude increases, the air pressure decreases. This results in lower boiling points for water because there is less atmospheric pressure pushing down on the water. However, the freezing point of water is not significantly affected by altitude.


Can water boil at a freezing point?

Absolutely, if the pressure of the system is low enough water will boil even at it's normal freezing point.


What is the procedure for does salt affect the tempute rof the heating or freezing point of water?

When salt is dissolved in water, the freezing point of water drops and the boiling point of water elevates.


What is true about the melting point and freezing point of water?

The melting point and freezing point of water is the same at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric pressure. This means that water will transition from solid to liquid (melting) or liquid to solid (freezing) at this temperature.


Does salt affect the temperature of water -boiling point - freezing point?

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.


How does salt affect the water's melting point?

Adding salt to water the freezing point decrease.
