vocabulary for the unit Solids, Liquids, Gases
Question | Answer |
---|---|
solid | matter that has a definite shape and definite volume |
liquid | matter that has an indefinite shape but a definite volume |
gas | matter that has an indefinite shape and an indefinite volume |
surface tension | uneven forces acting on the particles on the surface of a liquid |
plasma | is high energy matter consisting of positively and negatively charged particles |
viscosity | a measurement of a liquid's resistance to flow |
crystalline solid | is a solid that has its particles arranged in specific repeating order |
amorphous solid | is a solid that has its particles arranged in a random order |
cohesion | the attraction between molecules that are alike |
vapor | The gas state of a substance that is usually a solid or liquid at room temperature |
kinetic molecular theory | an explanation of how particles in matter behave |
Pressure | is the amount of force applied per unit of area |
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 |
kinetic energy | energy of motion |
Charles’s law | states that the volume of a gas increases with increasing temperature, if the pressure is constant. |
absolute zero | The lowest possible temperature at which particles no longer move |
temperature | measure of the average kinetic energy of all the particles in an object |
potential energy | stored energy resulting from the interactions between particles and objects |
thermal energy | total potential and kinetic energy of an object |
