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.
