1. have you ever made microwave popcorn? if so, what do you hear while the popcorn is in the microwave?2. if you turn the microwave on for two minutes, is the rate of popping always the same, or does it change? explain.

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 !
