Gases & The Ideal Gas Law 2.1 2.1.1 Phases of Matter Phases of Matter There are 3 phases of matter: solid, liquid, and gas. We need to have a general understanding of each one to understand how a phase change occurs. For example, for the phase change of a solid→ liquid, energy is required to break apart some of the strong intermolecular forces that solids have! Solid Don't fill the volume or take the shape of their container (have a fixed volume and shape) Hard Are not fluid like liquids and gases (don't flow unless extreme shearing/stretching forces) Has the strongest intermolecular forces Liquid Don't fill the volume of the container, but take the shape of their container Fixed volume, not shape since if you transfer the liquid to a different container the volume of liquid will remain the same but the shape of the liquid will change depending on the shape of the container Fluid Has the weaker intermolecular forces Liquid Don't fill the volume of the container, but take the shape of their container Fixed volume, not shape since if you transfer the liquid to a different container the volume of liquid will remain the same but the shape of the liquid will change depending on the shape of the container Fluid Has the weaker intermolecular forces
