why does popcorn seem to pop at a somewhat consistent rate regardless of the amount, instead of all of them popping closer to at the same time?

Question

why does popcorn seem to pop at a somewhat consistent rate regardless of the amount, instead of all of them popping closer to at the same time?

Answer 1

It is the same as boiling water. Boiling water consumes energy and energy is supplied at a consistent rate, so water also boils at a consistent rate. Popping a popcorn is basically boiling water inside the shells. The high pressure of water vapor causes the the shells to pop.
