Mini-investigation question 1: What will happen when you mix equal amounts of hot and cold water? What is your prediction for question one? Why do you think this will happen?

Conduct the investigation: On one of your paper cups write a mark at about of the cup. You will use this mark to make sure you use the same volume of water in each investigation. Measure out cold water from the tap (just use the coldest water you can get) to the marked line in your cup and pour into one of the other cups. Measure out hot water from the tap (just use the hottest water you can get) to the marked line in your cup and pour into one of the other cups. Use your thermometers to measure the temperatures. Temperature of hot water = _______ C Temperature of cold water = ______ C Predicted final temperature when they are mixed = _______ C Prepare to use your stopwatch. Pour the two liquids into a third cup and measure the final temperature. The final temperature is relatively stable, so when the temperature stops changing, you've reached the final temperature. Measure the time it takes to reach this stable temperature. Actual final temperature = ______ C Time it took to reach a stable temperature: ______ Is there a difference between your prediction and what you observed? What might be an explanation for this?
