Because reporters aren’t scientists.

The article links directly to a page on the law so maybe a little grace could be given?

It is why they feel hot to human touch though :)

Educate us please?

Motors and appliances get hot because inefficiencies eventually become waste heat. That is the source of the heat. It propagates from tbe heat source to a surface you can feel through conduction and other mechanisms.

Thanks!

Motors become hot because they generate heat through friction and other forms of loss. Many other appliances generate heat this way (and some are designed to generate heat).

Conductive materials are likely to be good heat conductors because the electrons themselves can conduct heat, and because the crystal structures of conventional metals (e.g. copper) tend to be good for both.

These two effects are entirely unrelated.

Thanks, that makes sense.

The relationship is generally true for metals (https://en.wikipedia.org/wiki/Wiedemann–Franz_law) but an appliance being warm to the touch because you use it is not really related.

Making relatable analogies is hard.

but, if anything, the opposite is true. If I keep dumping a constant amount of heat onto a material it will get hot enough to cool itself.

So a piece of aluminum will be cooler than a piece of iron. The Al might transfer more heat to my fingers than the steel... or it might not (that depends on many more factors than just the conductivity).

That's not an analogy, it isn't explaining something in terms of something else.

Analogy : a comparison of one thing to another for the purpose of explanation.

That's exactly what your parent said.

Parent: "That's not an analogie, it isn't explaining something in terms of something else."

You: "Analogy : a comparison of one thing to another for the purpose of explanation."

Well, the parent says this isn't an analogy, as it's not "comparing one thing to another for the purpose of explanation".
