Term
kinetic theory of matter
Definition
States that all of the particles that make up matter are constantly in motion
Term
temperature
Definition
is a measurement of the average kinetic energy of all the particles in an object
Term
degrees
Definition
are equally spaced units between two points
Term
thermometer
Definition
measures temperature through the regular variation of some physical property of the material inside the thermometer
Term
heat
Definition
is a flow of energy from an object at a higher temperature to an object
Term
thermal energy
Definition
is the total random kinetic energy of particles in an object
Term
calorie
Definition
the amount of energy needed to raise the temperature of 1 gram of water by 1 C
Term
joule
Definition
is the standard scientific unit in which energy is measured
Term
specific heat
Definition
the amount of energy required to raise the temperature of 1 gram of a substance by 1 C
Term
conduction
Definition
is the process that moves energy from one object to another when they are touching physically
Term
conductors
Definition
are materials that transfer energy easily

convection
Definition
is the process that transfers energy by the movement of large numbers of particles in the same direction within a liquid or gas
Term
radiation
Definition
is energy that travels as electromagnetic waves, which include visible light, microwaves, and infrared lights
