A student does an experiment to find out how the speed of sound waves changes when traveling in different mediums (solid, liquid, gas). The table below shows the different speeds of the sound wave in each medium but does not list the specific medium.

The student knows that sound travels through room temperature air at 343 m/s. Using this information and the student's results, which medium is the solid, the liquid, and the gas?

To determine the correct identification of mediums from the student's speed data, you need to know that sound travels fastest in solids, followed by liquids, and slowest in gases.

Given the information that the speed of sound in room temperature air (gas) is 343 m/s, we can draw some conclusions based on typical speed ranges for sound in different mediums:

  • Solids: Sound travels faster, typically ranging from about 1,000 m/s to over 5,000 m/s, depending on the type of solid.
  • Liquids: Sound speed is generally slower than in solids but faster than in gases, typically around 1,400 m/s to 2,000 m/s.
  • Gases: As we noted, sound travels at about 343 m/s in air.

If you can match the speeds derived from the experimental results to these categories, you can identify the mediums.

Since we don't have the table with specific speeds to analyze, I can’t provide a definitive answer based solely on the options given. However, knowing that the speed in gas will be around 343 m/s, you would look for the lowest speed in your data to identify the gas.

The correct statement typically would be:

  • A (lowest speed) is the gas,
  • B (medium speed) is the liquid,
  • C (highest speed) is the solid.

Given the options, without specific speeds listed, the correct response would likely be:

  • A is the gas, B is the liquid, and C is the solid.

If you provide the speed values, I can help clarify the specific identification.
