The change in state from a solid to a liquid
Question
The change in state from a solid to a liquid
Solution
The change in state from a solid to a liquid is called melting. Here are the steps involved in this process:
-
Increase in Temperature: The process starts with an increase in the temperature of the solid. This is usually done by applying heat.
-
Absorption of Heat: The solid absorbs the heat, which causes the particles in the solid to gain energy and start vibrating faster.
-
Breaking of Bonds: As the particles vibrate faster, the bonds holding them in a fixed position start to break.
-
Movement of Particles: Once the bonds are broken, the particles are able to move more freely. They are still close together, but they can slide past each other.
-
Formation of Liquid: As more heat is absorbed and more bonds are broken, the solid eventually turns into a liquid. This is the point at which melting has occurred.
-
Continuation of Heating: If heat continues to be applied, the liquid will eventually turn into a gas through the process of evaporation.
