Match the following gases with their proportion.
Gases Percentage by volume 1. Argon (a) 0.03 2. Carbon dioxide (b) 0.0018 3. Hydrogen (c) 0.94 4. Neon (d) 0.01
Atmospheric Gases Proportion Matching
This question requires matching specific atmospheric gases with their approximate volume percentages. Understanding the composition of Earth's atmosphere is key to answering this correctly. Let's break down the matching based on the provided options and the correct pairing.
Detailed Gas Proportion Matching
The task is to align each gas (Argon, Carbon dioxide, Hydrogen, Neon) with its corresponding percentage by volume. Based on the correct answer provided, the matches are as follows:
| Gas Name | Option Letter | Percentage by Volume |
|---|---|---|
| 1. Argon | (c) | 0.94\% |
| 2. Carbon dioxide | (a) | 0.03\% |
| 3. Hydrogen | (d) | 0.01\% |
| 4. Neon | (b) | 0.0018\% |
Understanding Atmospheric Gas Percentages
Here's a brief look at the gases and their typical proportions in Earth's atmosphere to understand the context:
- Argon (Ar): This is the third most abundant gas in the atmosphere, making up a significant portion. The value 0.94\% aligns with its known abundance.
- Carbon dioxide (CO2): While present in smaller amounts compared to Nitrogen and Oxygen, it's a crucial greenhouse gas. 0.03\% is a commonly cited approximate value, although current levels are slightly higher.
- Hydrogen (H2): Hydrogen is a very scarce gas in Earth's atmosphere. The value 0.01\% provided in the matching is significantly higher than its actual trace concentration, but it's the match indicated by the correct option.
- Neon (Ne): Neon is an inert gas found in trace amounts. The percentage 0.0018\% closely represents its actual volume percentage in the atmosphere.
Therefore, the correct matching, as derived from the provided options, is Argon with 0.94\%, Carbon dioxide with 0.03\%, Hydrogen with 0.01\%, and Neon with 0.0018\%.

- Prof. Murthy likes to let her students choose who their partners will be; however, no pair of students may work together for more than seven class periods in a row. Alice and Bob have worked together for seven class periods in a row. Calvin and Denny have worked together for three class periods in a row. Calvin does not want to work with Alice. Who should be assigned to work with Bob?
- Of four agents Alpha, Beta, Gamma and Delta, three have to be sent together on a mission. If Alpha and Beta cannot go together, Beta and Gamma cannot go together and Gamma and Delta cannot go together, then which of the following holds?
- In an experiment one group of subjects was asked to estimate the product of $8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1$ in 5 seconds. The other group was asked to estimate the product of $1 \times 2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 8$ in the same time. The former group attained a larger estimate than the later group. The biasing effect involved in this case is because of
