This is a question that would help with the understanding of specific heat and conductivity and which has a greater effect when it comes to transfer of energy between objects.
If the question is about that, then it should be clear that this is what it's about. In other words, the question could be something like:
"How do the thermal conductivity and specific heat influence the amount of heat transferred between two objects?"
And the body of the question would contain what you think the influence is, why you think that, and what part of that line of thinking makes you unsure of the answer. You could then give an example -- water causes worse burns than metal at the same temperature, and they have X and Y for the thermal conductivity and specific heat capacity, but you don't understand why it behaves that way.
That would be an entirely answerable conceptual question. This is of course just a rough idea of what the final question could look like, but hopefully it explains the general things that go into making a good, clear conceptual question.
And note, the specifics of the setup -- that you're interested in burning skin, the temperatures of the objects, that it's only held by gravity, etc. are all not required for the conceptual question. It could be about transferring heat between any two, different objects with different properties. That all makes it general and useful to other people down the road, rather than being tied to a specific instance with a specific setup.
