Everything is made up of molecules. These molecules are never still. They are always wiggling around being pulled by different forces.
Look! Now you’re doing chemistry
Bonding
The molecules are all held together by bonds. These bonds are like holding hands with another person. You can hold on tight or you can hold on loosely. You can pull together or you can be stretched apart. You can be pulled apart with force or you can twirl around each other.
As the temperature increases, the molecules move faster. The faster they move, the more bonds they break. The molecules then spread out, bouncing all over everywhere. They are now a gas.
When the molecules are at room temperature they are wiggling a little with kinetic energy. In this state they are loosely bonded to the other molecules. They can hold on, there aren’t many forces pulling. This is why liquids flow.
Charles Law
When heat is added, the molecules begin to move faster and faster. This causes them to need more space and pressure to increase.
As temperature increases, pressure increases.
Why Should You Care?
If the molecules have room to defuse (spread out) all is good.
