heat & transfer

• Heat energy

  Thermal energy
• Heat or heat energy is also known as thermal energy
• Conduction and Convection


  • Forms of heat transfer due to the movement of particles of matter
• Heat transfer in form of radiation

  Electromagnetic radiation or waves
• Heat transfer


  Transfer of heat energy from one location to another by the motion of particles colliding into each other
• Heat transfer

  1. Conduction: Transmission through collisions between neighboring atoms or molecules within the material

  2. Convection: Transmission by the physical movement of fluid (liquid, gas, or plasma) from one location to another

  3. Radiation: Process where heat waves are emitted that may be absorbed, reflected, or transmitted through a colder body
• Radiation


  • Form of heat transfer that does not require a form of matter
• Heat


  Flow of energy between two systems by means of kinetic energy. This can take the form of transferring energy from a warmer object to a cooler object
