Video of Lab
Our video is showing what happened when we tried our lab please be quiet and thanks for watching!
Science!
3 States of matter
The states of matter in our project are solid liquid and gas. It might surprise you ,but actually smoke is a collection of all three, it has tiny particles of all three states of matter. Visible smoke is usally carbon (soot), tar, oils, and gas. Then there is tinfoil and matches, which are both solids. We also had fire which is a gas.
Special effects
The special effects we did in our lab was fake smoke without dry ice. We did this by lighting matches and when we blow the matches out the cold beaker contained the smoke. This gave off the effect that we made.
Phase changes
At first the matches in the tinfoil were solid, then when you strike the matches there is fire, which is solid to gas (sublimation) and a chemical change. The chemical change being, that when you strike a match the particles in the match head and the particles in the striking board on the side of the box of matches, react to each other to create fire. When you blow the fire out there is smoke. Smoke is a form of, as said before, all three states of matter. Smoke is formed by the fire burning the wood.
Motion of Molecules
The matches in the tinfoil stayed a solid the whole time and the molecules stayed tight together. By lighting the matches in the experiment you get fire, fire being a gas, the molecules will move fast at a random pace speeding around each other. Smoke being all three has different molecules, solid (close together in a uniform setup), liquid (still close together but more random and can move past each other), and gas (fast, random, going past each other).
Molecules in a Solid
As is shown the molecules in a solid move slowly and are compact.
Molecules in a Liquid
As is shown the molecules in a liquid move past each other but still fairly close.
Molecules in a Gas
As is shown the molecules in a gas move fast and go past each other. They are also spread apart.
