WebMar 27, 2011 · A phase change is a physical change because the substance undergoing the change does not have a change in chemical composition. What type of change … WebA phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. The melting point is the temperature at which the substance goes from a solid to a liquid (or from a ...
