In your "cold frying pan" scenario...
The pan does not "trap" heat at all.
It's an example of "heat transferance"...
-- Through "thermal conduction".
However, when the pan reaches the same temperature as the burner...
The pan will begin to emit the same amount of heat as the burner itself.
And, for all intents and purposes...
The heat from the burner...
Simply passes straight through the pan.
I'd say that's pretty much the same as...
Putting a sponge under a running faucet.
When the sponge absorbs it's capacity...
For all intents and purposes...
The water from the faucet...
Flows right through the sponge.
Sorry Vince...
I still don't see one heckuvva lot of difference there.
In the meantime...
How deep do you think the Water's going to be...
When the Sea Slugs...
Have Finished Feasting on...
-- Our Oceans' Sponges...?
