Solid: It has particles that are stuck to each other firmly so it cannot be compressed and made into a different shape. Liquid: It is a bit similar to the particles in solids but this time there is little distance between each particles so they can move around. Gas: The particles are spread out well to make use of all the space. The gas particles spread out by themselves rather than sticking onto each other.

Questions: What is sublimation? To convert a solid (by heat) into gas form without turning it into liquid. Supposing you increased the pressure of the air above the boiling liquid. What would happen to the boiling point of the water? The water particles are trying to turn into gas but they are being pressured so they would require more energy (higher temperature/energy) to beat the pressure and successfully become a gas particle. Imagine that you are trying to boil water for a cup of tea up a mountain. Why would the cup of tea taste horrible? The pressure of air caused by the altitude and the tea will be too hot.
