Complete the calculations on slide 14 and mark your answers using slide 15. Thats why they move past each other but dont get very far apart from one another. Adding heat energy to particles either raises the temperature and they move faster, or bonds are broken to change from solid to liquid (melting) or liquid to gas (boiling). The particles in the diagrams could be atoms or molecules or ions, depending on the type of substance, eg The internal energyof particles is the kinetic energy they have due to their individual motions and potential energy due to their positions relative to eachother.

Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam. fixed shape and positions, vibrate but least energetic. A more general name for this class of material is biological materials. How much of our Universe is dark matter, and what evidence is there for its existence? The particles move around randomly and faster than in a solid or liquid. This is because the particles move faster with more kinetic energy. Solid chunks can form in the milk and cream. bbc.com.
