A student does an experiment to find out how the speed of sound wave 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 the specific medium.

Question

Medium
Speed Before (m/s)

4,440
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, liquid, and the gas?
(1 point)
• A is the solid, B is the liquid, and C is the gas.
O A is the liquid, B is the gas, and C is the solid.
• A is the gas, B is the liquid, and C is the solid.
• A is the gas, B is the solid, and C is the liquid.

Answer 1

To determine which medium is the solid, liquid, and gas based on the speeds of sound, we can use some general knowledge about the speed of sound in these mediums:

1. Sound travels fastest in solids, slower in liquids, and slowest in gases.
2. Given the speed of sound in room temperature air is approximately 343 m/s, this will help us identify the gas.

Let's evaluate the provided speeds:

• Speed A: 682 m/s
• Speed B: 1,293 m/s
• Speed C: 4,440 m/s

Based on the standard behavior of sound in different mediums:

• C (4,440 m/s): This is the highest speed, thus it must be the solid.
• B (1,293 m/s): This is the middle speed, so it must be the liquid.
• A (682 m/s): This has the lowest speed, therefore it must be the gas.

So the correct classification of the mediums is:

• A is the gas
• B is the liquid
• C is the solid

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