For a solid to melt it will gain/lose energy
WebFor most substances, the melting and freezing points are the same temperature; however, certain substances possess different solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting and freezing temperatures: it melts at 85 °C (185 °F) and solidifies between 31 °C and 40 °C (89.6 °F to 104 °F). WebAug 18, 2024 · Another way to list phase changes is by states of matter: Solids: Solids can melt into liquids or sublime into gases. Solids form by deposition from gases or freezing of liquids. Liquids: Liquids can vaporize into gases or freeze into solids. Liquids form by condensation of gases and melting of solids.
