Measuring CO(2) With Kernels of Millet

by | Sep 6, 2022 | Physics, Experiments

Introduction

In this experiment(measuring CO(2) with kernels of millet), we will be determining which temperature will have the most reciprocating motion of kernels of millet.

We hypothesised that as the carbonated water temperature decreases, the down-up motion of kernels of millet would acquire more frequency.

Aim

To find out the temperature at which kernels of millet have the most down-up motion.

Theory

1. Millet is grown all around the world. These small-seeded grasses act as human food for people living in different parts of the world.

2. Millets generally belong to the tribe Panicease.

3. A Kernel is the edible part of seeds and fruits.

Measuring CO(2) With Kernels of Millet

Types of Millets

Requirements

1. Twelve Lemon Lime Seltzer Sodas that had 1 degree, 6 degrees, and 22 degrees Celsius temperatures.

2. Thirty-Six kernels of Millet

3. Three beakers

4. A stopwatch

5. A thermometer

6. Notebook

7. Marbles

8. Metal bead

9. Plastic bead

Procedure

Step 1: Take three beakers and add lemon-lime seltzer sodas kept at three different temperatures in those beakers.

Step 2: Add kernels of millet to each of the beakers.

Step 3: Leave it for some time.
Step 4: Check the temperature of the beakers using a thermometer.

Step 5: For another experiment, sand a kernel of millet with sand to make it rough and harsh.

Step 6: Put an original and a rough kernel in carbonated water.

Step 7: Perform the same experiment using marbles, plastic beads, and metal bead

Step 8: Record your observations.

Observation

1. We observed three things that can prove beneficial in our everyday life.

2. For feeling fresh we got to know which temperature was the best for drinking carbonated water.

3. We can also determine which material is a poor conductor and which is a good conductor.

4. One can determine the roughness of materials.

Result

1. In the experiment that we performed at three different temperatures, which were 1-degree Celsius, 6 degrees Celsius, and 22 degrees Celsius, the carbonated water at 6 degrees Celsius had the most down-up motion.

2. This means that the carbonated water at 6 degrees celsius has the most active carbon dioxide.

3. This could be that the temperature difference between the beaker (6 degrees Celsius ) and room temperature (25 degrees Celsius) causes heat exchange between these two, which causes the greatest carbon dioxide emission.

4. When we performed the experiment with marble and metal beads, to check which one emits the most carbon dioxide. At first, we found that metal beads produce more carbon dioxide on their surface, but it produces less carbon dioxide after a while.

5. Among all (plastic bead, millet, marble, metal bead), the plastic bead had the most down-up motion for a longer time.

6. From our second experiment, we observed that the rough kernel produced more bubbles of carbon dioxide on its surface than the original kernel.

Precaution

1. Record your observation carefully.

2. Make sure the thermometer is working properly.

Conclusion

In this experiment, “measuring CO(2) With Kernels of Millet”, we determined at which temperature kernels of millet have the most down-up motion and also which kernel among original and rough has produced the most bubbles at its surface.

Viva Questions With Answers
