WebThese phase changes happen at specific temperatures, which results in ranges of temperatures where the substance will be in each phase. As the diagram shows, there is a specific temperature for the change between solid and liquid, and another temperature for the change between liquid and gas. WebPhase Changes Matter exists as one of three phases: solid, liquid, or gas. The phase of a substance depends on its thermal energy and temperature. Substances exist in the gas phase at higher temperatures and in the solid phase at lower temperature. The liquid phase occurs between these temperatures.
