How Does the Surface Area to Volume Ratio Affect Heat Loss in Organisms?

Use ice if you need to. Then, fill one beaker with 175 mL of water and the other with 350 mL. Warm the water in the 350mL beaker up to 55 degrees celsius and cool the water in the 175mL beaker to 15 degrees celsius, the same temperature as the pitcher because it will be your control group. Once the beaker that should be heated is at 55 degrees celsius, pour 175 mL of the water into a glove and pour the other 175 mL into a ziplock baggie. Pour the 15 degrees celsius, 175 mL of water into another ziplock baggie. Before you set these in water, have a stopwatch ready and make sure that the water in the baggies and glove is at the right temperature.

The measuring cylinder was then used to accurately measure out 20 mL of water, which was then poured into the test tube that would be used for the experiment. The test tube was then placed into the clamp, which was then adjusted in order to make sure that the test tube was grasped firmly and would not fall out.

hot. After the flask was clamped with a condenser into 400mL of boiling water. The condenser was to

Next, I poured distilled water just below the 250ml mark on the neck of the volumetric flask.

Step 3: Use the thermometer to identify and record the temperature for room temperature, in your refrigerator, in your freezer, and then research the temperature of boiling water (do not take this temperature) and record them in Table 2.

27. Heat the water to 40°C with an alcohol lamp by setting up the apparatus as shown in figure 3 below:

17) Pour a small amount of the hot solvent into the flask containing the solid.

4. Continue this process until data is obtained for at least six different temperatures. Be sure that the temperatures represent a large range of values in order to help you answer questions about the relationship between temperature and volume.

13. The temperature of the water was measured prior to the tube being placed in it and the temperature of the Hydrochloric Acid was measured after it 's temperature had adjusted.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.

2. Fill a flask with pure water (0% sugar), another with 0.2M water, another flask with 0.4 M water, and another flask with 0.8M water.

b) An empty beaker was weighted. Then, water was filled in the beaker. The temperature was recorded at uniform intervals.

Empty and clean the test tubes and repeat steps 2-10 again for a second dataset.

Rinse the thermometer with tap water and dry. Insert the thermometer in the calorimeters top and measure the initial temperature of the base 28.2∘C
