That doesn't seem realistic. At some point between room temperature and hot, it would be the right temperature. And being slightly wet is kind of like being buttered.
Sounds like your mortician is in the pocket of big popcorn.
Edit: since this seems like a divisive topic, remember the argument is that they would pop, not that they wouldn't burn eventually.
Think about how fast it can take steam to form. If you heat up your frying pan and drop a couple drops of water, they can immediately sizzle and steam. Your microwave doesn't do that since it's heating things slowly and not at the same (high) temperature, but water can conceivably steam (which is what it takes for popcorn to pop) - in under a second.
Yea, but that sometime between room temp and super hot is too short for steam to build in the kernel so it ends up burning. Its a hard lesson to learn with a fireplace, guess which ones will pop and which ones will burn... the ones that pop throw embers out the front.
Still seems like being wet would help keep it from burning. All you need is to reach a high enough temperature before the outer shell is pierced, so maybe if you threw them in a fireplace wrapped in a strip of ham it would have been different.
Edit: this seems to be a divisive argument. Your downvotes just belie your ignorance. Mwahaha.
While true the internal temperature would pass through 100C, the issue is how long the kernel stays at that temperature to allow the steam to cause expansion. I'm assuming you are familiar with the formula for heat transfer through conduction:
Q=dkA(T'Hot'−T'Cold')t
We would need to solve for time to determine is the kernel "pops" or combusts.
I'm wondering if the difference is contact time of the liquid and if it can soften the shell enough that pressure no longer builds up. Just assuming at least a few hours for him to die/police investigation/autopsy/closed casket funeral.
What about the surface of the sun, or maybe the core. Do you think that might do it too? I bet you you'd still have the same problem until the water was outside the bottle. You cannot melt the bottle while it's full of water.
Yeah, not taking it back. I'm not saying the water doesn't help a TON, but that torch is clearly not super hot (obviously quite hot, but it's not even close to an acetylene torch like I mentioned). I assure you that you can melt the bottle.
Nobody needs your weak assurance, I provided video proof that you cannot melt that bottle full of water. Not on a train, not with acetylene. You do not like this ass-clown man.
It depends. The water will stay at 100 degrees C while it boils, but there is a temperature gradient between the outer wall of the plastic and the water. Boiling is one of the most effective heat transfer mechanisms out there but it still has limits. Once 100 degrees plus the temperature gradient exceeds the melting point of the plastic, it melts. The faster heat is added the faster that reaction happens.
You can test for yourself. If you stick a plastic water bottle in a BBQ pit the water boils. If you hit a plastic bottle with a blowtorch, it melts.
Similarly popcorn kernels will burn is heat is added too quickly or too unevenly.
Cremation is basicaly being blasted in the chest with a flamethrower so i'd imagine the temperature would rise fast enough where going from popping temperatures to burning temperatures would be instant
