Atoms and Molecules

Atoms and molecules are the building blocks of all matter. Multiple atoms together come to form a molecule. An example of a molecule is sugar and citric acid, which is known as orange juice.

Atoms and molecules are part of heat because the atoms are always moving and the movement creates the heat. As atoms get hotter, they move more faster and more uncontrollably. The hotter atoms collide with they much colder and slower atoms, making them as hot too. An example of this situation is when your spoon touches your hot soup. The much faster moving atoms inside the soup collide with the much slower moving atoms, making them hot as well. Another example of such happen when you leave ice cream out in the open for it to melt. The ice cream has very slow atoms but when it becomes more heated than the atoms slowly get faster.

Atoms and molecules in a solid, liquid, gas, or plasma states have either low or high density rates.
Atoms in a solid are tightly packed together and are not free to move around as much. Solids have a definite shape and definite volume. In liquids, however, the atoms are allowed to move freely and the atoms are less packed as they are in a solid. Liquids have no definite shape and they take the form of the container they are in. Liquids also have a definite volume. In gases and plasmas, the molecules much farther apart then solids and liquids. These two states of matter don't have a definite volume or shape and are able to move around freely in unquestionable amount of space.
