Corey's Science Experiment 1. Purpose: To determine the effect that completely burning a log has on the weight of the log and to calculate the amount of energy transferred in the process. 2. Corey selects a log for the project. 3. He completely burns the log in a controlled environment. 4. He collects all of the ashes and soot which remain after the burning is complete. 5. He weighs all of the remains and calculates the amount of weight and energy transferred in the burning. What is wrong with the steps of Corey's experiment? A. The log was going to completely burn; therefore, there wouldn't be any ashes left to measure. B. He didn't set a time limit on how long he was going to let the log burn. C. He didn't measure the weight of the log before it was burned. D. He didn't have a partner there in order to verify the results.
