Test: Middle School Physical Science
1. | You are doing an experiment where you pour different amounts of hot water into the 200mL of cold water and measure the final temperature. The purpose of a “control” in an experiment is to see what would happen if you did NOT do a test. If we are testing how the volume of warm water effects energy transfer, which cup is our control? |
200 mL of hot water
200 mL of cold water + 200 mL of hot water
200 mL of cold water
an empty cup
