Yes. The freezing point of water (melting point of ice) depends on both the temperature and the pressure.

One easy way to lower the pressure is to add salt to ice. This lowers its freezing point and caused it to melt. Salt is spread on street and sidewalk ice in some areas to melt it and the addition of salt to ice is also used in the cooling of ice cream.

Is the melting point of water a physical or a chemical change?

First of all, melting point is not a change at all, so forget about classifying it as a physical or a chemical change. It's a property and it's got nothing to do with the chemical composition of water since when water melts it's chemical nature does not change. Hence melting point of water is a physical property or characteristic.


What method can you use to change the boiling point of water?

By melting


How can you tell that the melting of ice cube is a physical change?

You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.


What Physical Property of water changes when it reaches its melting point?

Its physical state. When it reaches its melting point, it will change from a solid to a liquid.


How does melting point change as the water content of rocks increases?

As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.


What's the melting point of water in Celsius?

The melting point of water is zero degrees Celsius.


What do melting point have to do with phase change?

The melting point of a substance is the point at which it goes from being a solid to a liquid. Like, as everyone knows, the melting point of water is 32°F, so if you had an ice cube it would melt when it reached 32°F. So the melting point tells you when a state change would take place in a substance.


What is a temperature at which solids start to change from a liquid?

The temperature at which a solid starts to change into a liquid is called the melting point. At this point, the solid absorbs enough heat energy to overcome its intermolecular forces and transitions into a liquid state.


Which physical property of water changes when it reaches melting point?

The transition from solid to liquid is a state change. Its ability to flow changes.


Is a melting points a physical or chemical change?

Melting point is a physical property, not a change.


What point does it become a liquid?

The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.


At what temp does water change to from a solid to a liquid?

The melting point of ice is at 0 0C.
