Guida verificata passo dopo passo1
Identify the phase change processes involved with solids, liquids, and gases. Each process describes a specific transition between states of matter.
Condensation is the process where a gas changes to a liquid, so it does not describe solid to liquid transition.
Sublimation is the process where a solid changes directly to a gas without passing through the liquid phase.
Evaporation is the process where a liquid changes to a gas, so it also does not describe solid to liquid transition.
Melting is the process where a solid absorbs heat and changes into a liquid, which matches the description of solid to liquid transition.
