This is the melting point.
Decreasing the temperature a liquid become a solid.
It is the melting point of the solid, the temperature of which depends on the solid.
it depends on what type of liquid it is
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
To change liquid water into a solid, you need to lower the temperature below 0 degrees Celsius to freeze it. To change liquid water into a gas, you need to raise the temperature above 100 degrees Celsius to evaporate it.
A rise in temperature
Drop the temperature.

In a word, temperature. A physical change will change the matter's state based on it's temperature. For example, water, H2O. You can increase the temperature to 212oF and it will change state from a liquid to a gas. You can decrease the temperature to 32oF and it will change state from a liquid to a solid. To answer your question, the process of doing so would be increasing or decreasing temperature of matter.
To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.
