Well, I agree. But what I mean is that when people ask physics questions, it is often implicitly understood to mean under current conditions. You rarely hear normal people or kids (who I find asks most of the physics question) include anything about frictionless vacuums in the question. (For reference: https://xkcd.com/669/ ). So, for the egg question, regular people would most likely consider the answer to be "No, except under very special circumstances". But, I agree with you that if a simple Yes/No answer is expected, it have to be Yes.
Wouldn't that be true for everything then? 3,400C is pretty special circumstances in my book, yet we say tungsten melts.
I don't think adding heat is a special circumstance like adding pressure is. It's very easy to add heat to something. Adding pressure means building a sealed environment to enclose it's, and some specialized equipment to increase the pressure.
Adding heat requires that you burn something. That's it.
Yes, you have a point. However adding heat is often implicit when talking about melting stuff. However, if it requires 3400C, then the answer would probably include a comment about that.
