Solid liquid or gas
Question | Answer |
---|---|
Solid | closely packed particles cause matter to have 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 | An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together. |
Viscosity | A liquid's resistance to flowing. |
Temperature | the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. |
Liquid | a type of matter with specific properties that make it less rigid than a solid but more rigid than a gas. |
Gas | a substance that has no fixed size or shape. |
Melting | When a solid changes to a liquid |
Melting point | the temperature at which a substance melts. |
Freezing | When a liquid changes to a solid |
Freezing point | the temperature when a substance freezes. |
Vaporization: | When a liquid changes to a gas |
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. |
Pressure | gas particles constantly collide with one another and the walls of their container. Pressure is the outward push divided by the area of the walls of the container |
Charles’s Law | When the temperature of a gas at a constant pressure is increased the volume is increased, if the temperature is decreased then the volume is decreased. |
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, if the temperature is decreased then the volume is increases. |
Inversely proportional | When the value of one variable increases, the other decreases. |
