## Presentation Transcript

Slide2Energy the ability to do work or to change something  used whenever the location, makeup or look of something changes

Slide3Thermal energy the total energy of motion of particles in a system  measure how fast the particles move and how many are moving  energy due to moving particles that make up matter  felt as heat

Slide4Temperature measure of the average amount of motion of particles in matter  measured with a thermometer in degrees Fahrenheit or Celsius  high temperature – the particles move fast  low temperature – the particles move slowly  does  not  measure how much heat the material has

Slide5Conduction the transfer of heat energy by one thing touching another  conductors  allow heat to move through them – metals like aluminum, iron, copper  insulators  limit the amount of heat that passes through it –wood, plastic, marble

Slide6Insulators

Slide7Conductors

Slide8Convection Current a pattern of flowing heat energy  forms when gas or liquid transfers heat as it moves  Heated 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.

Slide9Radiation the transmission of energy as light  comes from the sun or a fire  can travel through matter or empty space  absorbed by dark-colored or dull surfaces  reflected by light or shiny surfaces  passes through clear materials
