Heat Transfer

• Hot transfers to cold things.
• If the temperature is equal, there is no transfer transfer.
• The three types of heat transfer are conduction, convection, and radiation.
• Conduction is the physical contact through solid.
• Convection transfers through liquid and gas. (paakyat)
• Convection

  • density - high & low
  • temperature - high & low
• It is easier to move when it's hot
• mainit -> gagaan -> aakyat
• Radiation - pagilid

  • vacuum
  • electromagnetic wave
  • infared
