WebNov 8, 2024 · Adding heat to a sample changes part or all of it from solid into liquid ( melting ), or from liquid into gas ( boiling ). Having heat exit a sample can result in the phase changing in the opposite direction: liquid to solid ( freezing) or gas to liquid ( condensing ). WebConduction Conduction is a process by which heat is transferred from the hot area of a solid object to the cool area of a solid object by the collisions of particles. In other words, in solids the atoms or molecules do not have the freedom to move, as liquids or gases do, so the energy is stored in the vibration of atoms.
