Observations for Phase Changes

1. Solids, Liquids and Gases-Observe how by adding and taking away energy can affect matter
1. Neon
1. Neon's natural state must be solid because when you left it at room temperature it became a solid. In the slid, the particles were packed very close to each other and they were vibrating and moving left and right in the container.
2. When I added energy, the particles spread out and became a gas very quickly. They spread out and were obviously trying to get out.
3. For the liquid, they spread slowly and were quite attached to each other although more free than the solid state.
2. Argon
1. Argon's solid state was much like all other solid states; all of the particles were squished together and were moving left to right rather slowly.
2. When I added energy it quickly became a liquid and then even quicker it became a gas with particles flying all over trying to get out of their container.
3. The liquid particles started in a solid shape and then spread out slowly into liquid particles. They spread out more and more.
3. Oxygen
1. As you probably all know, there have to be two atoms attached to each other to make oxygen happen, and an oxygen is originally a gas. In the gas 'structure', the particles were all flowing around quickly and in the mean time turning in circles.
2. In the liquid, the particles started in a circle form and spread a bit but also stayed together more than the two above.
3. In the solid shape, the particles were in an orderly fashion and vibrated, but didn't move around that much.
4.  Water
1. The particles in the liquid state moved around very quickly and turned over each other, but were still connected.
2. In the gas particles they were moving around freely very quickly, like most of the other gases.
3. In the solid, the particles were moving around quite slowly and were very attached to each other by the hydrogen and oxygen atoms.
2. Phase Changes
1. Neon
1. When the neon was a gas it took 453 K for the lid to come off because of too much pressure.
2. Argon
1. The argon was a gas with  2,548 K for the lid to pop off and because of too much pressure.
3. Oxygen
1. This gas started at 193 K and went all the way to 2,430 K until the lid would pop off.
4. Water
1. This gas started at quite a high kinetic energy, 809 K and went to 5,347 K for the container to explode
