Let’s say my family is taking a day hike across Hawaii and, not having a map, are just aimlessly walking. We come across a volcano. My brother, being the less intelligent, yet more handsome version of myself, decides he wants a closer look. He ventures further, when all of a sudden, the volcano starts erupting.
So minutes later, he’s surrounded by molten lava, flowing down the hill.
Factoring out noxious and dangerous gasses, how long does my addle brained brother have to live until he bursts into flames? Does the heat from lava dissipate quickly enough to not raise the surrounding atmosphere to unbearable temperatures? Am I destined to become both more intelligent and better looking?
