Answer 1

1. Popping
2. No the rate of the popping is not always the same , the Corn pops at different rates depending on the amount of heat conducted into the popcorn itself . If you were to conduct an experiment and put 2 different bags in 2 separate microwaves , they’d sound and pop all over the place and in different rates. The more heat , the faster the popcorn pops !
