Phases of Matter

What are the phases of matter?
There are 4 phases of matter named: Liquid, Solid, Gas, and Plasma. Liquid is described as having particles and molecules are not close together and not concentrated. Solid has molecules very concentrated which makes it harder. Gas has its molecules very spread out which makes it less concentrated. Plasma is a gas that is composed of free floating ions.


How is on phase of matter different than another phase? There is a very big difference between the matter phases. Solid has a very focused energy which makes it harder. While a liquid is more soft and has a spread out molecules.

Design 3 tests that you can do to determine whether an object is on of the 3 common phases of matter? For a liquid you can let it drip to see if it has a spread molecules. We can test that by putting the liquid in a container and see if it will take the shape of the container. We know a solid is something that is hard. We can test that by putting it in a bag and if the same shape you know its a solid.

Flame Test

''A flame test is a procedure used in chemistry to detect the presence of certain metal ions, based on each element's characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color''.

http://en.wikipedia.org/wiki/Flame_test

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a bunsen burner. The heat of the flame converts the metal ions into atoms which become excited and emit visible light. The characteristic emission spectra can be used to differentiate between some elements.

Red Sludge

         On Tuesday, 5, 2010 a disaster happened in Hungary. The disaster was an, waste water spill spilled from a company called MAL. It was a very big disaster. The spill made big damage such as flipping over cars, getting into houses, and flooding farmlands. The disaster killed 4 people and injured 120. The sludge contain Bauxite the raw material from which aluminum is processed, contains a mix of minerals, including aluminum, iron oxides and titanium dioxides.

Lab Pictures

This is a picture of our second experiment. We made a triangle out of aluminum and poured the solution with the salt dissolved in the empty space. 

In this picture you can clearly see how the bubbles are forming on the aluminum.

 This pictures shows how the bottom of the aluminum has a hole built from the solution and the salt.

















This pictures shows how the copper divided the aluminum into small circles.

 This picture shows how the aluminum has been turned into copper and there is a bubble formed at the corner. The entire surface is covered with the copper.

 This pictures shows how there is parts of aluminum but most if the part is covered with the copper. This image looks like continent of Africa.

This picture shows how the copper got stuck on the spoon.
