Matter
| Term | Definition |
|---|---|
| Solid | a definite shape and definite volume. |
| Crystalline solids | particles form a regular repeating pattern called crystals. |
| Amorphous solids | particles not arranged in a repeating pattern |
| Surface Tension: | a liquid that brings the molecules on the surface closer together. |
| Viscosity | A liquids’s resistance to flowing |
| Evaporation | takes place only on the surface of the liquid. |
| Boiling | When vaporization occurs both below the and at the surface. |
| Boiling Point | Temperature at which a liquid boils. |
| Freezing | When a liquid changes to a solid |
| Freezing point: | the temperature when a substance freezes. |
| Evaporation: | takes place only on the surface of the liquid. |
| Boiling: | When vaporization occurs both below the and at the surface |
| Boiling Point | Temperature at which a liquid boils. |
| Condensation | When a gas changes to a liquid. |
| Sublimation | When a substance changes straight from a solid to a gas. |
| Charles’s Law | When the temperature of a gas at a constant pressure is increased the volume is increased |
| Directly proportional: | as one amount increases, another amount increases at the same rate. |
| Boyle's Law | When the pressure of a gas at a constant temperature is increased the volume decreases |
| Inversely proportional | When the value of one variable increases, the other decreases. |
| Melting: | When a solid changes to a liquid |
| Melting point | the temperature at which a substance melts. |
| Temperature: | the higher the temperature the faster particles moving. |
| Liquid: | particles are free to move so a liquid has a definite volume but no definite shape. |
| Reference Point | A place or object used for comparison to determine if something is in motion |
| Distance SI Unit | Meter (measures the length of a path between two points) |
| Speed | The distance an object moves per unit of time |
| Average Speed | Calculate the total distance traveled by the total time. |
| Instantaneous Speed | he speed at which an object is moving at a given instant in time. |
| Velocity | Speed in a given direction |
| Graphing Motion | Plotting time on the x-axis and distance on y-axis |
| Slope | is the steepness of the line, shows how fast one variable changes in relation of the other variable |
| Mechanical Energy | form of energy associated with the motion, position, and shape of an object. |
| Nuclear Energy | The energy stored in the nucleus of an atom. |
| Thermal Energy | The total potential and kinetic energy of the particles in an object. |
| Electrical Energy | The energy of electrical charges. |
| Electromagnetic Energy | The form of energy that travels through space in waves. |
| Chemical Energy | The potential energy stored in chemical bonds. |
