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
