#### Abstract:

The purpose of this experiment was to determine what the effect of different temperatures was on gas production. The hypothesis was if the temperature is lower, then the gas production will increase. The independent variable was the temperature (Â°C) of water with levels of 10Â°C, 20Â°C, 25Â°C, 50Â°C, and 75Â°C. The control is room temperature water, 20Â°C. The dependent variable was the amount of gas produced (mL). This is measured by finding the difference between the top of the jar, and the new water level after the gas subsides. The constants of the experiment included the same amount of water used for each replicate, the same amount of tablets used in each replicate. Three trials were run, with 5 replicates at each level. The data concluded that the hypothesis is rejected. In fact, all 3 trials showed that when the temperature increases, the gas production increases dramatically. With further experimentation, additional replicates with temperatures colder than 10Â°C should be run as it would further validate that as temperature increases, gas production increases.

Title: The Effect of Temperature on Gas Production

Question/Problem: What is the effect of temperature on gas?

Hypothesis: If the temperature is lowered, then gas production will increase.

Materials:

Alka Seltzer tablets: 75

Water: 18.75 L

500 ml bottle: 1

1 cm diameter, 10 inch aquarium tube: 1

Thermometer: 1

Paper towels: 15

710 mL glass jar: 1

2.5 liter glass bowl: 1

Marker: 1

X-acto knife

Tea kettle

Refrigerator

Measuring cups (mL)

Safety wear (apron, gloves, goggles, mittens)

Procedure:

1. Put 500 mL of water into the refrigerator for 30 minutes at 10°C
2. Pour 250 mL of the cool water into the 500 ml testing bottle
3. Mark the initial water level on the 710 mL glass jar with a marker
4. Test the water displacement device by doing steps 5 to 7
5. Immediately add two Alka seltzer tablets into the bottle of water and screw the cap on tightly quickly
6. Wait for the fizz to stop by seeing if bubbles in the drink are gone
7. Mark the new water level with a marker and find the difference between the changed water level and the normal water level before (this will be how much gas has been displaced from the fizz)
8. Record in Data table
9. Repeat steps 2-8 for 3 more times with hot water from the tea kettle (25°C, 50°C, and 75°C)
10.  When using the water from the tea kettle, pour cool water into the almost boiling water until it reaches the desired temperature
11.  Let 250 mL sit in room temperature for an hour and then repeat steps 2-8 once more

Data Analysis: The amount of gas produced in mL will be measured after bubbles and fizzing process subsides. The mean of 5 replicates and 3 trials of 5 levels of IV will be put into a data table. A graph showing the mean of the 3 trials that were used to find the amount of gas produced, and the different temperatures used, will be constructed.

Risk Analysis: Safety wear such as goggles, aprons, and gloves must be worn to avoid contact with any contaminated water and to protect from explosions. Adult supervision is required when setting up and doing the experiment.

How to build the carbonation measuring device

1. Cut a hole into the (500 mL testing bottle) bottle cap so that an aquarium tube with a diameter of 0.5 cm can fit through it and then glue it to the tube
2. Add 118 mL of water to the glass jar and mark the increment
3. Repeat Step 3 three more times, until about 472 mL have been reached
4. Fill a 2.5 liter glass bowl with ¼ water (625 mL) and fill the glass jar with at least 473 mL of water
5. Put the glass jar upside down into the bowl and mark the water level
6. Put the end of the aquarium tube that is not attached to the bottle cap and put it into the bowl and through the glass jar
7. Attach the half liter bottle to the bottle cap and test the contraption
8. The gas should travel down the aquarium tube into the glass jar, displacing the water
