Question

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?

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

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

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

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

To determine which medium corresponds to A, B, and C based on the speeds of sound in different mediums (solid, liquid, gas), we can reference general knowledge about the speed of sound in these mediums:

  1. Speed of sound in solids is typically the highest.
  2. Speed of sound in liquids is lower than in solids but higher than in gases.
  3. Speed of sound in gases is the lowest.

Given that the speed of sound in room temperature air (gas) is approximately 343 m/s, we can infer the following:

  • The highest speed corresponds to the solid.
  • The middle speed corresponds to the liquid.
  • The lowest speed corresponds to the gas.

Now, without the actual speeds provided in the table, let's analyze the options based on these principles:

  1. Option A: A is the liquid, B is the gas, C is the solid.
  2. Option B: A is the gas, B is the solid, C is the liquid.
  3. Option C: A is the solid, B is the liquid, C is the gas.
  4. Option D: A is the gas, B is the liquid, C is the solid.

The correct identification of the mediums based on their speeds should show the solid (highest speed), liquid (middle speed), and gas (lowest speed).

Given that we have defined the characteristics:

  • Solid (C)
  • Liquid (B)
  • Gas (A)

The correct response would therefore be:

Option C: A is the solid, B is the liquid, and C is the gas.
