This video shows you what happen when a solid is heated, it changes into a liquid and this process is called MELTING. When this liquid is heated it changes into a gas what it is called EVAPORATION. If a liquid cools down, it changes into solid tis process is SOLIDIFICATION or freezing. Same thing happens when a gas cools down, it changes into a liquid this is CONDENSATION.
Is everything clear? If not just ask me.
