A hairdryer uses 1500 J of electrical energy in 1 second. The hairdryer changes 1300 J of this to useful thermal energy in 1 second. Calculate the quantity of energy that is wasted by the hairdryer in 1 second. Show your work.

Sagot :

200 J of energy is wasted by the hair dryer.

Steps

  • The hairdryer is provided with 1500 J of electrical energy per second
  • Of this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per second
  • The remaining energy, 1500 - 1300 = 200 J is dissipated

Dissipated energy

  • The energy that is not efficiently transported or changed is wasted energy.
  • We cannot create or destroy energy.
  • An employable type of energy is created through transformation.
  • Only a portion of energy that is changed or transferred can be done so in a way that is helpful.

Thus, 200 J of energy is wasted by the hair dryer.
