Speed of Sound in Solids, Liquids, and Gases - Physics Practice Problems

This physics video tutorial provides a basic introduction into the speed of sound in solids, liquids, and gases. It contains plenty of examples and practice problems. In a solid, the speed of sound depends on the density of the material and young's modulus - also known as the elastic modulus. In a liquid, the speed of sound depends on the density of the fluid and the bulk modulus. In a gas, the speed of the sound depends on gamma - the ratio of heat capacities, the temperature, and the molar mass of a gas. As the temperature increases, the speed of sound in air increases. The speed of a solid is higher than the speed of sound in a liquid which in turn is higher than the speed of sound in a gas. All of the equations and formulas that you need are provided. This video contains examples and practice problems of calculating the speed of sound in steel, the speed of sound in water, and the speed of sound in air.

instructions unclear i'm crying rn

[@kuusupporter4634]

go do some tik tok

This really expand my knowledge rather than learning it from goverment text book

[@theboogiegamer3872]

Loved this video thanks a lot.... It will help me a lot in my exam. Give your blessings love you

Thank you dude

Extraordinary excellent

[@shivanihr5879]

If speed of sound is constant (344m/s) then why do we calculate speed of sound for different wavelengths, with the formula ... speed of sound = frequency x wavelength. Because there are numericals given in kid's textbook to find out speed of sound with the given frequency and wavelength. Some websites on Google says speed of sound is uniform (344 m/s) and does not depend on frequency or wavelength, when the opposite is clearly given in the formula. Please explain.

[@samanthakeilyn5927]

I'm confused

[@tanishranjan5]

Is young modulus equal to bulk modulus?

[@LoonaticOrbit]

Its the same

[@sauravjha1688]

No.
Y-used for length change
B- used for volume change

[@b-7garciarovictgabrielv.530]

THANK YOUUUUU!!!!

[@polatbor]

If the density of a solid is directly proportional to the speed of sound travelling through it, why is it indirectly proportional as stated in the first equation?

[@nick.......]

Because it's not directly proportional. Increasing density actually decreases the speed of sound.

[@lukasforsman7756]

why can't u use the bulk modulus when calculating the sound velocity in a solid.
please answer i really need help

What do need know to this answer?...!

How much horsepower would the Challenger Hellcat Redeye Widebody need to run the speed of sound arrive before the sound of its legendary engine arrives?

[@ACF11JULY24]

Great video

[@squishyhobi1700]

#1 explanation lol someone correct me w the units tho im not used to that but anyways:
sqrt 200x10^9 pa / 8000 kg/m^3 = sqrt 25000000 kg/m/s^2
- because thats like the other form of the unit pa since we have kg/m^3 so thats just for convenience
sqrt 25000000 kg/m/s^2 = 5000 m/s
- dont ask me about canceling units n stuff idk how it works lol but if someone wanna explain it to me do so please

[@akonalangsana9224]

Thanks but i hope you will lower up your volume next time :))))))))))

[@alexwizard152]

bruuhhh pls show how u calcuateeeee my brains hurts >_

[@fernandohood5542]

What happens if you have two gases e.g propane and butane at 90% to 10%?

[@carlamaegastardo1453]

My brain hurts...

[@Kirill-rc5ng]

Huh how did you solve that?

[@Hexiix]

Because he solve

[@physicshuman9808]

It is 343m/s

[@troy6882]

😃😄😁😆😅 5 Smiles and have a noted mixed gas love the mix top job👍😁. Want to see the wave harmonic for metals or the bridge replication all because off a light breeze????did you see the footage!😳or at barrier reaction for electrical and light??and the note to weight and why so close???warp not so easy is it startrek.😁.

[@markagusting695]

i tried to do it in my scical calculator and cant solve it

[@MouweE12]

show as the your calculation so we can know how you solve that!!

How do you solve without density

[@Alex_gaming853]

You have to calculate it first so that you can know if it's solving without density.

[@Player-cp6cp]

@@Alex_gaming853 yeah figured it out myself already but still thanks

[@maximilianalvarez737]

where did you get 0.6??

[@dilshankavinda9911]

It's an experiment value...speed of sound is approximately a multiplication of 0.6

[@spencerllewellyn8911]

Its a general rule of thumb. It doesn't really matter where he got it

[@alphonsajeyarani5881]

Better

I have never been so stupid

🥰🥰

[@itszhaye4046]

Whaattt????

[@damodarchintu8379]

velocity of sound is square root of( bulk modulus(K)/density) , where modulus of elasticity(E)=3K(1-2*poisson's ratio). please don"t teach wrong

[@trendteaser9333]

He taught everything right smh

[@dilshankavinda9911]

Speed of sound depends on medium that travel..not only bulk module...jg is not wrong

U just sovle the solution in speed of sound in air u didn't solve the speed of sound in solid nor liquid all of this video is just 1 topic what a watse

Steel is the solid, water is the liquid. Watch the whole video.
