Quiz - 2 - Diving Knowledge Workbook - Diving Physics

Of course they're talking about when you're diving-- for Pete's sake

Things like heat stroke while waiting on a boat in a wetsuit in the sun are very real concerns for divers and are very much issues with radiation and convection.

I understand that (and have often experienced being hot to the point of sweating a bit in my farmer john). We just disagree on the clearness of the question-- When I read this 11 years ago there was no doubt in my mind they were talking about when some one was in the water diving. I guess it could have been spelled out.
Heat stroke can also happen to someone who has nothing to do with being in a wetsuit and diving.

Not really. I totally agree that they're definitely looking for conduction as the answer here.

way to think globally! The way you put it, radiation is definitely disproportionally more important

Radiation is important when your body is surrounded by a medium which is transparent to infrared radiation (air).
But water is almost entirely opaque to infrared, hence there is no radiation exchange underwater...

I understand that. I think @couv jokingly was implying that “divers are most affected” by radiation from Sun, just like anybody else on Earth, as without this form of heat transfer the water would be in the solid state and the planet would be a chunk of ice in space. I took it as a joke as it is a cute way to think outside of the box and I replied rather jokingly.

Spoiler: Answer

a. Conduction

Conduction refers to the transmission of heat via direct contact. Convective and radiant transmission of heat are relatively unimportant to divers.
