IScience - Chapter 8 Vocab Flashcards
(18 cards)
Solid
Matter that has a definite shape and a definite volume
Liquid
Matter with a definite volume but no definite shape
Viscosity
A measurement of a liquid’s resistance to flow
Surface Tension
The uneven forces acting on the particles on the surface of a liquid
Gas
Matter that has no definite volume and no definite shape
Vapor
The gas state of substance that is normally a solid or a liquid at room temperature
Kinetic Energy
The energy an object has due to motion
Temperature
A measure of the average kinetic energy of all the particles in an object
Thermal Energy
The total potential and kinetic energies of an object
Vaporization
The change in state of a liquid into a gas
Evaporation
Vaporization that occurs only at the surface of a liquid
Condensation
The change of state from a gas to a liquid
Sublimation
The change of state from a solid to a gas without going through the liquid state
Deposition
The change of state of a gas to a solid without going through the liquid state
Kinetic Molecular Theory
An explanation of how particles in matter behave
Pressure
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 volume increases, when temperature is constant
Charles’s Law
States that the volume of a gas increases with increasing temperature, if the pressure is constant
