ELI5: Why it takes longer to heat up two hot pockets in a microwave than one.

Same applies to any food, obviously. I just happen to be consuming a hot pocket currently while staring vacantly at the instructions.  And does the same effect apply to normal ovens at all?

A conventional oven that heats up everything inside an oven including air, the oven sides, etc.  That's quite a waste of heat but if you put one or two hot pockets in the oven, you won't see much of a difference.

A microwave oven is much more efficient, which is why it's fast. It only sends energy to food you put in it.  Its energy output is limited though, so the more food you put in it, the less energy each part is getting.
