Slide1Three Types  of Heat  Transfer Three  Types  of Heat  Transfer 6 th   Grade 6 th   Grade Convection  and  the  Mantle Convection  and  the  Mantle

Slide2RadiationRadiation  The  transfer  of  energy  through  space  is  called  radiation .  The  transfer  of  energy  through  space  is  called  radiation .  Takes  place  with  no  direct  contact  between  a  heat  source  and an  object.  Takes  place  with  no  direct  contact  between  a  heat  source  and an  object.  Sunlight  is  radiation  that  warms  the  Earth’s  surface.  Sunlight  is  radiation  that  warms  the  Earth’s  surface.  Other  examples:  flame  or  open  fire.  Other  examples:  flame  or  open  fire.

Slide3ConductionConduction  Heat  transfer  within  a  material  or  between  materials  that are  touching  is  called  conduction .  Heat  transfer  within  a  material  or  between  materials  that are  touching  is  called  conduction .  Responsible  for  some  of  the  heat  transfer  inside  Earth.  Responsible  for  some  of  the  heat  transfer  inside  Earth.

Slide4ConductionConduction  In  conduction,  the  heated  particles  of  a  substance  transfer heat  through  contact  with  other  particles  in  the  substance. Conduction  heats  the  pan  and  the  contents  of  the  pan.  In  conduction,  the  heated  particles  of  a  substance  transfer heat  through  contact  with  other  particles  in  the  substance. Conduction  heats  the  pan  and  the  contents  of  the  pan.

Slide5ConvectionConvection  Heat  is  also  transferred  by  the  movement  within  fluids  – liquids  and  gases.  Heat  is  also  transferred  by  the  movement  within  fluids  – liquids  and  gases.  Convection   is  heat  transfer  by  the  movement  of  currents within  a  fluid/  Convection   is  heat  transfer  by  the  movement  of  currents within  a  fluid/  Heated  particles  of  fluid  begin  to  flow.  The  flow  transfers  heat from  one  particle  of  fluid  to  another.  Heated  particles  of  fluid  begin  to  flow.  The  flow  transfers  heat from  one  particle  of  fluid  to  another.  Heat  transfer  by  convection  is  caused  by  the  differences  of temperature  and  density  within  a  fluid.  Heat  transfer  by  convection  is  caused  by  the  differences  of temperature  and  density  within  a  fluid.

Slide6DensityDensity  Density   is  a  measure  of  how  much  mass  there  is  in  a volume  of  a  substance.  Density   is  a  measure  of  how  much  mass  there  is  in  a volume  of  a  substance.  When  a  liquid  or  gas  is  heated,  the  particles  move  faster  and spread  apart.  As  a  result,  the  particles  of  the  heated  fluid occupy  more  space.  The  fluid’s  density  decreases.  When  a  liquid  or  gas  is  heated,  the  particles  move  faster  and spread  apart.  As  a  result,  the  particles  of  the  heated  fluid occupy  more  space.  The  fluid’s  density  decreases.  When  the  fluid  cools,  the  density  increases  because  the particles  slow  down  and  move  closer  together.  When  the  fluid  cools,  the  density  increases  because  the particles  slow  down  and  move  closer  together.
