2Energy the ability to do work or to change something used whenever the location, makeup or look of something changes
3Thermal energy the total energy of motion of particles in a system measure how fast the particles move and how many are movingenergy due to moving particles that make up matterfelt as heat
4Temperaturemeasure of the average amount of motion of particles in mattermeasured with a thermometer in degrees Fahrenheit or Celsiushigh temperature – the particles move fastlow temperature – the particles move slowlydoes not measure how much heat the material has
5Conduction the transfer of heat energy by one thing touching another conductors allow heat to move through them –metals like aluminum, iron, copperinsulators limit the amount of heat that passes through it –wood, plastic, marble
8Convection Current a pattern of flowing heat energy forms when gas or liquid transfers heat as it movesHeated air is less dense than cool air.Cool air sinks and the warm air is forced up.The cool air is warmed by the heat source and is forced up by more cool air.
9Radiation the transmission of energy as light comes from the sun or a firecan travel through matter or empty spaceabsorbed by dark-colored or dull surfacesreflected by light or shiny surfacespasses through clear materials
