    I came across effect of humidity on speed of sound and was confused why moist air was less dense than dry air. Thank you for clearing my doubt.

      and Firstly human mind simply think that moist air is more dense than dry air, so speed of sound is more in moist air than dry air 😂

    This was an extremely clear explanation! I think it would be really cool to show maybe 100 molecules or so and show the water vapor coming off a lake and rising through the atmosphere.

    All I want to think about in hot weather like today in UK is if the sounds outside are different pitch and louder or quieter.
    This video so good for making normal things outside home window sound fun and different at different times. Good for lockdown.

    Thanks for the good explanation and animation.
    Where exactly will the replaced O2 and N2 go ?
    will they go to another air volume, replacing other molecules .. and repeat? till what? what's the final destination of the replaced molecules.

    Why sound propagate faster in low density ..

    • @planes1mple296
      @planes1mple296 5 років тому +3

      The explanation is quite simple though. Here goes:
      A substance that is denser per volume has more mass per volume. Usually, larger molecules have more mass. If a material is denser because its molecules are larger, it will transmit sound slower. Sound waves are made up of kinetic energy. It takes more energy to make large molecules vibrate than it does to make smaller molecules vibrate. Thus, sound will travel at a slower rate in the denser object. If sound waves of the same energy were passed through a block of wood and a block of steel, which is more dense than the wood, the molecules of the steel would vibrate at a slower rate. Thus, sound passes more quickly through the wood, which is less dense.

  • @kevinvoorheis1990
    @kevinvoorheis1990 5 років тому +1

    I'm confused...why would the density change because it weighs less? By definition, density is The quantity of mass per unit volume. You said the quantity didn't change..so how did the density change? Weight has nothing to do with density.

    • @andrewhebert7883
      @andrewhebert7883 5 років тому +1

      Density is defined as weight/volume. If the weight decreases, but the volume stays the same, the density value will decrease. (The quantity of molecules in each jar is still 5 molecules per jar, but the molecules have different weights).

  • @Social_squad

    But there is something that I don't understand. You have just said that a dry air is a normal air with a combined mass of two molecular atoms of Nitrogen and two atoms of oxygen and you say that a moist air is just a normal air that has water vapor. If that is the case, why don't you add the total molecular weight of dry air with a total molecular weight of water vapor since they are joined together?

  • @redgeronimo1

    Why can't the water molecules occupy the space in between the nitrogen and oxygen molecules?

    • @redgeronimo1

      @@mustafasarca9590 Thank you. I did understand, basically the pressure applied , volume occupied and temperature of the nitrogen and oxygen molecules doesn't change (and an equal number of molecules only will fit in a well defined volume),so when one water molecule is forced to enter the atmosphere, either an oxygen or nitrogen molecule exits that well defined volume. However after all of this; the pressure applied by that well defined volume which contains water molecules decreases, but I presume that the number of molecules that can fit in that well defined volume remains the same .
      I wonder why the number of molecules must remain the same and not the number of atoms i.e the total a.m.u of the gases in that well defined volume.

  • @n1lknarf
    @n1lknarf 4 роки тому

    If moist air is less dense than dry air, could you please explain to me why the clouds even exist? I would assume that condensation cannot happen as long as the Sun's heat is hitting the water molecules, they would just get dry at some point. Even if many water molecules end up together the Sun's heat should still be able to dry them all... unless the Sun is not as hot as humans presume it is. I'm a bit confused about this. It would make sense if the moist air was more dense than liquid water somehow, but according to your video it just can't be so: how can the Sun evaporate liquid water but not gas water?

    • @Asbestoslover666
      @Asbestoslover666 4 роки тому +1

      im literally very dumb at physics.. but my best guess would be that because you're getting closer to space and the atmosphere is thinner, it is getting colder so it condenses? like when you're in an airplane its super cold outside, not super hot. so it doesnt get hotter and hotter from the sun, which you theorized would cause it to evaporate. thats just a guess though.
