If so, is the amount of heat transferred sufficient to cause first,
second or third degree burns?


A couple of tidbits of information:

1. "First Degree" = Reddening of the outer layer of the skin [Epidermis] ~
Sunburn, Scalding
2. "Second Degree" = Blistering of the outer layer of the skin ~ Severe
Sunburn, Severe Scalding
3. "Third Degree" = Charring of the outer layer of the skin ~ Backing up to
an operating Cutting Torch's flame

I have heard of a slightly different scale of this, which had more to
do with the damage inflicted. First degree burns don't destroy the skin,
second degree destroy the skin, but not the underlying tissue, third degree
burns destroy the underlying tissue. This could cause a "3rd degree" burn
from boiling water (or sugar solutions such as syrup or honey, which can
get much hotter than water).

It isn't so much the temperature, as it is the heat transferred.
Anyone who has passed their hand through a cutting torches flame or held a
hand over a small match, can tell you the difference. (I recall watching
the guy stick his hand into a pot of molten lead. Okay, he didn't keep it
in long, but he did "stick his hand in molten lead", and just as fast
jerked it out.)

I was "intrigued" to learn there is a new classification of "4th
degree" which is when the tissue and/or bone burn. Ouch.
