Why does sound travel faster in solids and liquids than in gases?

The reason of speed of sound is faster in solids and liquids than in gases.
Answer to Problem 9A
As the molecules are closest in the solid and rarest in case of gases. The speed of sound travel by the vibration so as the molecules are closest in the solids, so the speed of sound in faster in solids & slowest in the gases.
Explanation of Solution
Introduction: The sound is a wave which ravel through material medium.
The speed of sound in the steel is more than liquid and gases as in the solid there is very less space between particles. The speed of sound in liquid is more than the air, as in liquid the molecules are closer than the air. Thus, the speed of sound is faster in the solids & liquids than in gases.
Conclusion:
As the solids & liquids are closely spaced so the speed of sound is faster than in gases.

You are present for the testing of the ride, in which an empty 150 kg car is sent along the entire ride. Near the end of the ride, the car is at near rest at the top of a 100 m tall track. It then enters a final section, rolling down an undulating hill to ground level. The total length of track for this final section from the top to the ground is 250 m. For the first 230 m, a constant friction force of 370 N acts from computer-controlled brakes. For the last 20 m, which is horizontal at ground level, the computer increases the friction force to a value required for the speed to be reduced to zero just as the car arrives at the point on the track at which the passengers exit. (a) Determine the required constant friction force (in N) for the last 20 m for the empty test car. Write AK + AU + AE int = W+Q + TMW + TMT + TET + TER for the car-track-Earth system and solve for…arrow_forward
