There are many factors that affect the loss of energy:
1 the resistance of the wire
2 the kettle will keep most heat in but not all heat within the kettle so more energy is lost
3 the water will evaporate out the top and that is also a cause. (they can't close it off otherwise the pressure would build and it would explode).

What is the average percent of 100 percent 100 percent 100 percent?
100+100+100=300. 300/3 is 100
What is 84 percent out 100 percent?
84 percent out 100 percent = 21/25 or 0.8484%/100%= 84/100= 21/25 or 0.84
What is bigger 100 or 100 percent?
100 percent means 100 out of every 100, so it is effectively 1. 100>100%
Is it 100 percent have or 100 percent has?
Whether you say 100 percent have or 100 percent has depends entirely on the context of the statement. Examples are: (1) Of the people attending the meeting, 100 percent have complained about high taxes. (2) Getting a test score of 100 percent has a lot to do with your success in being hired.
What is 10 percent of 20 percent of 30 percent of 100?
10 percent of 20 percent of 30 percent of 100 = 0.1 x 0.2 x 0.3 x 100 = 0.6
Is a nuclear generator 100 percent efficient?
No, no machine is 100% efficient.
How efficient is a small space heater?
it is not very efficientAnswerThey are 100 percent efficient.
Are electric heaters 100 percent efficient?
No. Nothing is 100 percent efficient. In any situation some energy will be given off in a form that is useless to us.
Are turbines 100 percent efficient?
Basically, almost NO physical process is 100% efficient.
Explain why machines are not 100 percent efficient?
because they are not proper
When will frictionless engine be 100 percent efficient?
at 0'kelvin
What heat dissipation mechanism is lost when humidity approaches 100 percent?
Sweating is no longer efficient near 100 percent humidity.
Why are no machines 100 percent efficient?
Some energy is lost to friction.
What does it mean to say a radio is not 100 percent efficient?
Play a play a game
Why aren't machines 100 percent efficient?
becaus ethey have friction
Why may an electrical heater be 100 percent efficient?
They can never reach that level of efficiency.
What is the force that prevents all machines from being 100 percent efficient?
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
