How does adding thermal energy effect the particle motion of a gas?
Matter makes up everything around us. The air we breathe, the water we drink, the chair we are sitting on, the cells in our body, it is all made up of matter. Matter can exist in different states: Take water for example, it can exist as a solid (an ice cube), liquid (water in a cup for drinking), and gas (vapor rising from a boiling pot of water). In all three states, water is always made of the same molecules, H20.
