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.

What is a temperature at which solids start to change from a liquid?
the melting point
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.
What method can you use to change the boiling point of water?
By melting
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.
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 the melting point of water change as pressure increases from1atm?
Decreases
The change in a state of matter from a solid to a liquid?
This type of change is called condensation or liquefaction.
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
What is another way of describing a freezing point of change?
- Melting point change. ^.^
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.
Is a melting points a physical or chemical change?
Melting point is a physical property, not a change.
