PLEASE HELP ASAP Step 1

Using the sticky notes, label the thermometers T1 and T2. Make sure that both thermometers are at room temperature (around 21°C). Then, in the table, record their temperatures and the time of this initial measurement.

Step 2

Place 1 tablespoon of baking soda in the small glass or jar. Carefully add one-fourth cup of white vinegar. When the mixture starts to bubble or fizz, place the first thermometer (T1) near (not in!) the glass. Then cover the glass and the thermometer with one of the upside-down soda bottles. If the thermometer cannot stand vertically on its own or it is too large to lay horizontally within the soda bottle, it can lean against an inner side of the soda bottle.

Step 3

Immediately place the other soda bottle upside down over the second thermometer (T2). Place each bottle approximately 4 to 5 inches apart under the lamp or other heat source. Turn on the lamp to expose each bottle to heat. The lamp or heat source represents the radiant energy that Earth receives from the Sun. The gases inside the bottles represents two different atmospheric compositions. Determine how the amount of radiant energy absorbed by each atmosphere changes by tracking the temperature in the table.
