1
New cards
solid
matter that has a definite shape and a definite volume
2
New cards
liquid
matter with a definite volume but no definite shape
3
New cards
viscosity
a measurement of a liquids resistance to flow
4
New cards
surface tension
the uneven forces acting on the particles on the surface of a liquid.
5
New cards
gas
matter that has no definite shape or volume
6
New cards
vapor
the gas state of a substance that is normally a solid or liquid at room temperature
7
New cards
vaporization
the change in state of a liquid into a gas
8
New cards
evaporation
vaporization that occurs only at a surface of a liquid
9
New cards
condensation
that change of state from a gas to a liquid
10
New cards
sublimation
the change of state from a solid to a gas without going through a liquid state.
11
New cards
deposition
the change of state if a gas to a solid without going through a liquid state.
12
New cards
kinetic molecular theory
an explanation of how particles in matter behave.
13
New cards
pressure
the amount of force applied per unit of area
14
New cards
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.
15
New cards
Charles Law
states that the volume of a gas increases with increasing temperature, if the pressure is constant.
