| Question | Answer |
|---|---|
| The three most common forms, or states, of matter on Earth are? | solids, liquids, and gases. |
| most common state of matter in space? | plasma |
| Some ways to describe matter are... | describe the state, color, texture odor, and by using measurements such as mass, volume, and density. |
| The main factor that determines the state of matter are? | particles motion and particle forces |
| SOLIDS | matter that has a definite shape and a definite volume. Particles in a solid are close together |
| LIQUIDS | matter with a definite volume but no definite shape. Liquids can flow and take the shape of their containers. Particles move faster than a solid and in turn move slightly father apart. |
| Viscosity | a measurement of a liquids resistance to flow. Ex: honey has a high viscosity and water has a low viscosity |
| Surface Tension | the uneven forces acting on the particles on the surface of a liquid. |
| GASES | matter that has no definite volume and no definite shape. Particles move even farther apart than solids or liquids. Particles spread out to fill a container. |
| Vapor | the gas state of a substance that is normally a solid or a liquid at room temperature. |
| Melting | change of matter from a solid to a liquid. Thermal energy must be added. |
| Freezing | change from a liquid state to a solid state. |
| Vaporization | change from a liquid to a gas. |
| Sublimation | change of state from a solid to a gas without going through the liquid state. Ex. Dry ice |
| Deposition | change of state of a gas to a solid without going through the liquid state |
| Molecular Theory: | is an explanation of how particles in matter behave. *small particles make up all matter. *these particles are in constant random motion *the particles collide with other particles, other objects, and the walls of their contai |
| Pressure | is the amount of force applied per unit of area. When particles collide with their container, pressure results. |
| Pressure and Volume | when the volume is greater, the particles have more room to move (fewer collisions-pressure is less). |
| Boyle's Law: | states that pressure of a gas increases if the volume decreases and pressure of a gas decreases if the volume increases, when temperature is constant. |
| Charles Law | states that the volume of a gas increases with increasing temperature, if the pressure is constant. |
| At absolute zero or 0 K (kelvin) | all particles are at the lowest possible energy state and do not move. |
