All the power absorbed by the heating element and the connecting wire is converted into heat, leading to the 100% efficiency figure.
No. Nothing is 100 percent efficient. In any situation some energy will be given off in a form that is useless to us.
it is not very efficientAnswerThey are 100 percent efficient.
100 %
Sweating is no longer efficient near 100 percent humidity.
They can never reach that level of efficiency.

No, no machine is 100% efficient.
Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.

Basically, almost NO physical process is 100% efficient.
Only if you're referring to an electric heater ... since all loses are also heat. The real world answer is no.
because they are not proper
at 0'kelvin

Some energy is lost to friction.
Nothing or anything that converts energy is 100% efficient because as one form of energy is converted into another form, some energy is lost in that of heat, sound or other factors. The most efficient form of energy is the fuel cell as it converts chemical energy in electrical energy directly but still it's not 100% efficient. A2. I think that an electric convector heater would be 100% efficient, as it has no moving parts to lose energy through friction, all the electric energy absorbed in the device is emitted as thermal energy.
