Phase change

A phase change is when a state change into another  the three conventional states are gas , liquid , and solid there are a few ways a phase change can happen in nature one way way is  evaporation when water goes from a liquid to a gas then when it condenses on  dust particles in the sky  forming clouds then when the  water gets to heavy it rains or snows  so the water cycle is a good example of a phase change and also when water freezes and turns into s solid so that is my understanding of phase changes thank you for reading.

  1. I think it is fantastic how liquid can change into solid or gas.
    May I challenge you a little? What is the name of a phase change when solid changes directly into gas without going through liquid stage first? Water can do that.
    You are learning a lot!!!
