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
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
Is a nuclear generator 100 percent efficient?
No, nuclear generators are not 100 percent efficient. They typically have an efficiency rate of around 30-40%, which means that 30-40% of the energy from the nuclear reactions is converted into electricity, while the rest is lost as heat.
Why are no machines 100 percent efficient?
Some energy is lost to friction.
Why aren't machines 100 percent efficient?
becaus ethey have friction
Are transformers 100 percent efficient?
No because it will lose electron by core losses and winding losses
What are some reason that machines are not 100 percent efficient?
friction and entropy the production of heat with in a system
How efficient is a kettle?
Very - probably well over 90%. An electric kettle is very efficient, especially if the body is made from plastic rather than metal; almost all of the electrical energy used goes into heating the contents rather than the container. A metal bodied kettle used on a gas stove would be significantly less efficient.
Are electric heaters 100 percent efficient?
No, electric heaters are not 100 percent efficient. While they convert all the electricity they consume into heat, some heat can still be lost through the material of the heater itself, especially if it is not well insulated. Also, some heat may escape into the surrounding environment instead of heating the intended space.
Why 100 percent heat not convert in mechanical work in engine?
No engine is 100% efficient: there is always some loss of energy between input and output.
What temperature is required to transfer waste heat to the environment for a heat engine to be a 100 percent efficient?
In order for a heat engine to be 100 percent efficient, the temperature of the cold reservoir where waste heat is transferred should be absolute zero (0 Kelvin). This is not achievable in practice, as it violates the second law of thermodynamics.
