Matt Wolbers 9/18/07 Lab Report: Water Cooling Abstract - In this experiment we used a Bunsen burner to heat water and watched the rate it cooled. We started off by measuring the air temperature, which was 22 degrees Celsius, and then heated the water to 80 degrees Celsius and let it cool to 75 degrees. After that we took the temperature at every two minutes and recorded it until it reached 35 degrees Celsius. Introduction- This experiment we are testing the cooling of air and the rate at which it cools. Experimental Procedures- Step 1- Record the air temperature of the room. Step 2- Fill the beaker with 50 ml of water. Step 3- Set up the Bunsen burner and the ring stand. Place the ring stand about three inches from the flame and place the beaker on the ring stand. Step 4- Heat the water to 80 Celsius Step 5- Let the water cool to 75 C and record the data every two minutes to the nearest .5 C Step 6- Continue recording until 35 C Step 7- Clean up experiment.
