Fluids, gases, and solids
Question | Answer |
---|---|
condensation | The process of changing state from a gas to a liquid. |
Density | The mass of a given volume. A way to describe how closely particles are packed together in a solid, liquid or gas. |
Evaporation | The process of changing state from a liquid to a gas |
Expansion | an increase in volume cause by a decrease in external pressure |
Mass | The amount of matter in a substance or an object; the more matter, the greater the mass. |
Melting | The process of changing state from a solid to a liquid |
melting point | The temperature in which a solid starts to liquefy |
boiling point | The temperature in which a liquid changes into a gas. |
Solidification | the process of changing state from a liquid to a solid by the removal of heat. |
Sublimation | the process of changing state from a solid to a gas without going through the liquid stage. |
volume | The amount of space taken up by a substance or object. |
formula for density? | Mass divided by volume |
Kinetic molecular theory | describes how adding energy to particles makes them move faster and further apart. |
Particle model of matter | Describes how particles of solids are closer together than particles of liquids. Particles of a gas are spread far apart. |
kinetic energy | the energy of motion |
