An Example of How Planets Are Created
Do you want to know how the planets are created? Here is a simple example to comprehend this matter further. We pour some water into a container and add sugar to it. Then, we heat this mixture. The heat creates motion in water and sugar and initiates their mixing. Some of the substances in the container turn into steam and gas due to this heat. Some of this steam moves into the air, while the rest circulates and boils inside the container.
As the heat increases, the velocity of movement of the particles of this mix increases. When this mixture is abundantly heated, then a part of the steam evaporates, while some of it remains in the mix. What remains in the container gradually becomes denser and solidifies. In other words, the mixture boils so much due to the heat that it creates a solid object.
However, when it took this solid-state, alongside that rigid and material portion, some of that ascending gases, and other gas and steamy particles remain around it and encompass the object.
