-
the energy an object has because of its motion
kinetic energy
-
a theory explaining the states of matter, based on the concept that all matter consists of tiny particles that are in constant motion
kinetic theory
-
results from the force exerted by a gas per unit surface area of an object; due to collisions of gas particles with the object
gas pressure
-
a space where no particles of matter exist
vacuum
-
the pressure exerted by atoms and molecules in the atmosphere surrounding Earth, resulting from collisions of these particles with objects
atmospheric pressure
-
an instrument used to measure atmospheric pressure
barometer
-
a unit of pressure; it is the pressure required to support 760 mm of mercury in a mercury barometer at 25°C
standard atmosphere (atm)
-
the SI unit of pressure
pascal (Pa)
-
the conversion of a liquid to a gas or a vapor
vaporization
-
vaporization that occurs at the surface of a liquid that is not boiling
evaporation
-
the temperature at which the vapor pressure of a liquid is just equal to the external pressure on the liquid
boiling point (bp)
-
the boiling point of a liquid at a pressure of 101.3 kPa or 1 atm
normal boiling point
-
the temperature at which a substance changes from a solid to a liquid; the melting point of water is 0°C
melting point (mp)
-
a solid in which the atoms, ions, or molecules are arranged in an orderly, repeating, three-dimensional pattern called a crystal lattice
crystal
-
the smallest group of particles within a crystal that retains the geometric shape of the crystal
unit cell
-
one of two or more different molecular forms of an element in the same physical state; oxygen (O2) and ozone (O3) are allotropes of the element oxygen
allotrope
-
describes a solid that lacks an ordered internal structure; denotes a random arrangement of atoms
amorphous solid
-
transparent fusion product of inorganic materials that have cooled to a rigid state without crystallizing
glass
-
the process in which a solid changes to a gas or vapor without passing through the liquid state
sublimation
-
a graph showing the conditions at which a substance exists as a solid, liquid, or vapor
phase diagram
-
the point on a phase diagram that represents the only set of conditions at which all three phases exist in equilibrium with one another
triple point
