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.
Medium A, speed before 682
Medium B, speed before 1,293
Medium C, speed before 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, the liquid, and the gas?
Options:
A is the gas, B is the liquid, and C is the solid
A is the liquid, B is the gas, and C is the solid
A is the solid, B is the liquid, and C is the gas
A is the gas, B is the solid, and C is the liquid
To determine which medium is the solid, liquid, and gas, we can compare the speeds of soundwaves in each medium to the speed of sound in room temperature air (343 m/s).
From the given information:
- Medium A has a speed of 682 m/s before
- Medium B has a speed of 1,293 m/s before
- Medium C has a speed of 4,440 m/s before
Comparing these speeds to the speed of sound in air (343 m/s), we can make the following conclusions:
- Medium C has the highest speed (4,440 m/s), indicating that it is the solid. Solids typically have faster sound velocities compared to liquids and gases.
- Medium B has a slightly slower speed (1,293 m/s), suggesting that it is the liquid. Liquids generally have intermediate sound velocities.
- Medium A has the slowest speed (682 m/s), indicating that it is the gas. Gases generally have the slowest sound velocities.
Therefore, the correct answer is: A is the solid, B is the liquid, and C is the gas.
