| What is matter? | anything that has mass and takes up space |
| What are all forms of matter made of? | tiny, constantly moving particles |
| Matter has properties that can be | observed and measured |
| How are the properties of matter determined? | in part by the arrangement of the particles that make it up & in part by properties of the particles themselves |
| A solid has? | a definite shape and a definite volume |
| A liquid has? | a definite volume but no difinite shape |
| A gas has? | neither a definite shape nor a definte volume |
| According to Boyle's Law | a decrease in the volume of a certain amount of gas will result in an increase in its pressure |
| According to Charles' Law | an increase in the temperature of a certain amount of gas will result in an increase in its volume |
| A physical change is a change in what? | change in the size, shape, or phase of matter |
| A chemical change occurs when? | new kinds of particles are created |
| Chemical changes may produce what? | heat or light, create bubbles of gas, or form a new solid |
| What is the idea that matter are made up of tiny particles that are in constant motion? | particle model |
| Why are diamonds, graphite, and soot have different properties? | the carbon is arranged differently |
| How does speed of a particle movement change with temperature? | as temperature increases the speed of the particles of matter increases |
| Temperatures high enough to form plasmas naturally exist where? | in stars |
| Plasma is called the _______ phase of matter and is the most common phase of matter in universe. | fourth |
| What are plasmas formed from? | the gases hydrogen and helium |
| What properties do plasmas have that gases do not? | conduct electricity |
