In reply to the discussion: Did he fake a bullet wound?? [View all]LeftInTX
(34,317 posts)I'm looking at a study and it looks like the bullet stays under 100 degrees C. So, it looks like the average from an AK is 63 degree C. So, I'm guessing about 150 degrees F??? So, the "burning" would minimal. 150 degrees can burn, but I've exposed my feet to it momentarily and so have many others. Our sidewalk and walls hit that temp here in Texas. A car door on a very hot day can likely reach that temp. 150 degrees is probably something our fingers have encounter frequently in the kitchen. Generally boiling point is when you can expect redness from brief contact. I know you can stick your finger in a pot of boing water for a second and nothing happens, however handling the same pot will cause burns.
Based on the contact time, I think any burning would be minimal.
As a comparison: The space shuttle is traveling around 20,000 mph. The same with meteors. A bullet travels at 2,000 mph. The space shuttle and meteors are larger than bullets too.
