ELI5: Why is it that if you cook popcorn for 20 seconds too long the whole bag tastes burnt but the the first few kernels to pop can seem to withstand the microwaves heat for up to several minutes?

What's up that?

While there are still a lot of unpopped kernels and only a few already popped, the energy is absorbed by the unpopped kernels. It is only until a few unpopped kernels are left, that the already popped kernels start to absorb energy and get burnt.
