You recently read an article saying that popcorn that was kept in the refrigerator

pops better. You have two equal bags of popcorn, one that was on the shelf and one

that was in the refrigerator. You pop both bags of popcorn for the same amount of

time using the same microwave, then measure how much popcorn you get from

each.

Know the Answer?

Zack Garner · Answer 1

B is the best answer

Shiloh Mcintyre · Answer 2

The correct answer will be option-B.

Explanation:

An experiment is performed to test the predicted and proposed hypothesis.

The experiment contains two types of group of samples: the experimental group on which the variable is to tested (independent variable) and the control group in which the independent variable is kept constant.

In the give question, the hypothesis is the popcorn which is kept in the refrigerator pops better so the independent variable will be cold temperature. So the experimental group will be the samples which are kept in cold temperature or refrigerator as the cold temperature is provided in these samples.

Thus, Option-B is the correct answer.
