Compare and contrast the movement of solid, liquid, gas, and plasma particles. What is the difference between physical and chemical properties of matter? Give 3 examples of each.

To create "dry ice," manufacturers compress and cool carbon dioxide gas until it solidifies. Describe what happens to the carbon dioxide molecules as the gas is compressed and cooled.

All life that we know of is based on carbon. Carbon's ability to form many chemical bonds is an important characteristic that allows it to form the basis of life. Identify two other elements that can probably also form a large number of bonds and that probably have similar properties to carbon. Explain your answer.
