The speed of sound in a particular medium depends on temperature and pressure of that medium. The speed of sound decreases when it passes from solid to gaseous state of a given medium . ... For example, the speed of sound in air at 0 0 C is 331 m s – 1 and at 22 0 C it is 344 m s – 1 .
Why is the speed of sound through medium C 0 m's )?
The speed of sound in air at 20 o C is 343.2 m/s which translates to 1,236 km/h. The speed of sound in gases is proportional to the square root of the absolute temperature (measured in Kelvin) but it is independent of the frequency of the sound wave or the pressure and the density of the medium.
Why is the speed of sound through medium?
The phase of matter has a large impact upon the elastic properties of a medium. In general, the bond strength between particles is strongest in solid materials and is weakest in the gaseous state. As a result, sound waves travel faster in solids than in liquids , and faster in liquids than in gasses.
In which medium the speed of sound is 0 m s?
| Medium v (m/s) | Hydrogen 1290 | Liquids at 2 0 ° C 2 0 ° C | Ethanol 1160 | Mercury 1450 |

Why speed of sound is fastest in solid medium?
Sound travels fastest through solids. This is because molecules in a solid are packed against each other . When a vibration begins, the molecules of a solid immediately collide and the compression wave travels rapidly.
Which state of matter can make sound travel faster?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Why does sound travel faster in helium?
As stated above, sound waves travel faster in solids than they do in liquids than they do in gases. ... Thus, a sound wave will travel nearly three times faster in Helium than it will in air. This is mostly due to the lower mass of Helium particles as compared to air particles.
Which medium will sound travel the fastest?
Sound waves travel faster and more effectively in liquids than in air and travel even more effectively in solids. This concept is particularly hard to believe since our general experiences lead us to hear reduced or garbled sounds in water or behind a solid door.
In which medium speed of sound is highest?
Speed of sound is maximum in solids and decreases from solids to liquids and liquids to gases. Sound can't travel through a vacuum. Sound travels at different speeds depending on what it is travelling through. Temperature also affects the speed of sound.
Which medium would sound travel the slowest?
As a rule sound travels slowest through gases , faster through liquids, and fastest through solids.
In which metal speed of sound is maximum?
The speed of the sound wave will be maximum in steel .
How many MPH is speed of sound?
If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph , or 1100 feet/second.
Does speed of sound depend on medium?
The speed of sound varies greatly depending upon the medium it is traveling through. ... The more rigid (or less compressible) the medium, the faster the speed of sound. The greater the density of a medium, the slower the speed of sound.
Can sound waves travel in vacuum?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space , where there are no atoms or molecules to vibrate.
Why does sound travel faster in aluminum?
Sound in Aluminum
Sound travels at one of the fastest rates through aluminum, at 6,320 meters per second. This is because aluminum is not particularly dense–meaning that it has little mass in a given volume–and is extremely elastic and capable of changing shape easily .
How does temperature affect speed of sound?
Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. ... The speed of sound is also affected by other factors such as humidity and air pressure .
