3 Ways of Heat Transfer

Convection

Conduction

Radiation

conduction
Conduction
  • Conduction--transfer of heat between atoms as they collide within a substance
  • 2 objects touching
convection
Convection
  • Convection is the movement of matter due to differences in density that are caused by temperature
  • Important in weather, plate tectonics, and ocean currents
radiation
Radiation
  • Radiation is the transfer of energy by electromagnetic waves, such as visible light and infrared waves
  • Key form = sunlight
phases of matter
Phases of Matter
  • There are 3 main phases of matter:
    • Solid, Liquid, and Gas (a 4th is sometimes included—plasma)
    • Each phase requires a certain amount of kinetic energy
solids
Solids
  • Require the least amount of energy
  • Very low particle movement
  • Usually associated with low temperatures
  • When solids gain enough energy they change through a process called MELTING
liquids
Liquids
  • More energy than solids, less than gases
  • Take the shape of their container because they have more freedom to move than solids
  • Liquids can lose energy to become solid through a process called FREEZING
  • Liquids can also gain energy to become gases through a process called EVAPORATION
gases
Gases
  • Have the most energy of the 3 phases
  • Particles move around very freely
  • Usually associated with high temperatures
  • If gases lose energy (temperature), they can change back to a liquid through a process called CONDENSATION
