Energy Transfers in Everyday Appliances

• What are the energy tranfers of a fan and blender ?

  electrical energy -> kinetic energy
• What is the energy transfers of a kettle and iron?

  Electrical Energy -> thermal energy
• Why do kettles and irons not transfer kinetic energy?

  they are designed to heat up and not for movement
• What energy does washing machines and hair dryer transfers?

  electrical energy -> Kinetic energy + thermal energy
• What is power rating ?

  How many joules of energy is transferred per second
• How can you tell a material is good conductor of heat ?

  if the temperature decreases in a shorter time because the rate of energy of transfer is higher
