    In the comment section of the outdated video, I made a "nooo" comment on the words "oxygen molecule", and it can still be seen in the pastebin.
    However, my response to the replies confirming that O2 is indeed a molecule, got lost. I responded something along the lines of "I believe that it's called "dioxygen" because there are 2 oxygen atoms" (the atoms forming the dioxygen molecule).
    It was brave to edit a whole portion of the video for that mistake. I applaud you for that.

    • @carultch
      @carultch 3 года назад

      Oxygen is understood to mean oxygen's simplest elemental form, which is the two atom molecule. Unless otherwise specified, "oxygen" as a substance name refers to O2, with no need for a prefix to tell us that there are two atoms. Single atom oxygen is unstable in our atmosphere, and three atom oxygen is called ozone. The terminology also works the same way for nitrogen, hydrogen, and the halogen family, where the element name refers to its default elemental form, as a homonuclear diatomic molecule. Single atom forms of these elements are also unstable, so the two-atom form is what the element name means by default.

    3:50 Let this be a lesson to all us smart people. When asking a "normal" person what the mass of something is just say "How heavy is it?". They may not know the answer but they will know what your talking about then.

    • @donlitos

      No, the heaviness or 'weight' of an object does not indicate the mass, just as you would have the same mass on earth as you would on the moon but a different weight

    Thumbs up! Another informative way to explain this would be to recast the ideal gas law in terms of density - i.e. pressure ~ density * temperature. An additional, interesting notation would be to explain the role of the decreasing ambient density & why we can't fly right into space!

  • @peteryoung8462
    @peteryoung8462 9 лет назад

    As mentioned, weather balloons don't have a hole at the bottom, so they keep getting bigger until they burst. Unless.... They enter a cloud with super-cooled water drops in them, and start accumulating ice. Then they get heavy and start to fall- into warmer air where the ice melts. And they can bounce around for hours around the same height, and if they are fitted with a radar reflector, they make a great impersonation of an unidentified aircraft in distress.

    You could mention that altitude is maintained when the total mass of the balloon and the air inside it equals the amount of air it displaces. To increase altitude i.e., get up where the air is thinner, the air inside the balloon has to get hotter.

    • @donlitos
      @donlitos 4 месяца назад

      Close, but not quite. The mass of the air inside and outside the balloon can remain the same at all altitudes. It is the relative weight of the air inside the balloon, not its mass, that causes it to rise when heated.

  • @radguitar1
    @radguitar1 9 лет назад

    I try to explain this to people as often as I can; we live at the bottom of our ocean at air, and that gravity is what makes planes (and balloons) fly.

    • @carultch
      @carultch 3 года назад

      I would disagree on gravity being the reason planes fly. Gravity is one of the forces to account for in airplane flight, but it has nothing to do with the reason the wings generate lift, or the reason the engines generate thrust. You could in theory fly a plane in a zero gravity environment with the air at uniform density, on the same working principles that actual planes use to fly. The same cannot be said for aerostat aircraft like balloons.
      An aerostat aircraft (lighter than air) like a balloon or blimp needs a pressure gradient in the surrounding air to be capable of floating in the air. A pressure gradient that is generated because of gravity and every layer of air, supporting the cumulative air above it.
      An aerodyne aircraft (heavier than air), like an airplane or helicopter could in theory work in a zero gravity environment with initially uniform air pressure and density, if it were built for it. The shape of an airplane wing, and the arrangement of helicopter rotors are built with offsetting gravity in mind, so it would be difficult to fly a standard toy aircraft on the ISS. You'd need a neutral shaped wing with bidirectional ailerons, for an airplane to control its flight in a weightless environment. A drone is probably a more practical aircraft for this experiment, if its propellers could be spun in both directions.

    well done but as nitin said it already i think there is a mistake too at 5.10 about why ships float, the weight of displaced water is equal to the weight of ship, the reason is density, ship has overall lower density due to its air filled bottom. This problem came up on the physics girl channel and even I had it wrong :'(

    i was always curious about how you navigate the balloon. don't you drift away due to winds? Is there a way to control the horizontal direction?

    • @besmart
      @besmart  9 лет назад +1

      +pranao walekar Balloons travel at the mercy of the wind. Winds move different directions at different altitudes, though, and experienced pilots can read those winds and navigate the balloon up and down to travel on different air currents. In some of the time-lapses I shot, you can actually see balloons moving in different directions at different altitudes. It's pretty cool.
      Thanks to the mountains and valleys surrounding the city, Albuquerque, NM (where this was shot) actually has some really special winds that are great for ballooning. It's called the "Albuquerque Box" and when conditions are just right, balloons can return to exactly where they take off! Here's a cool explainer on that: wildcardweather.com/2014/10/09/the-albuquerque-international-balloon-fiesta-and-the-albuquerque-box/

      John, the winds travel in different directions, at different altitudes. We go up and down to find the steering winds.We have competitions where you have to steer to a target and drop a bean bag on the target. You cannot fly in a hot air balloon that great of a distance, don't carry that much fuel. Average flight is about an hour and a half.

    if you make a vacuum chamber that, when depressurised, weighs less than its volume in air would, would that float?

      Gautham Thampy then make it bigger untill it works... a sphere of steel bars with a strong, airtight material around it. As you make it bigger, the volume will increase faster than the steel.

      Gautham Thampy surface area is ^2 and volume ^3 so eventually it will pass eachother.

      @@kalebbruwer The problem is that you need a pressure vessel to maintain the vacuum. And in practice, that structure will be more dense than the air itself, even when you evacuate it to a perfect vacuum. By using hot air or helium, which can be at nearly the same pressure as the surrounding air, it allows for a much lighter container to contain the less dense region of space, which means we can actually take credit for the hot air or helium reducing the density and making aerostatic flight possible.
      Ever held a CRT monitor or television? It is HEAVY. There is a vacuum chamber inside, and you would think that would make it light. The structure of the tube is what makes it heavy. All that glass and metal housing, to contain the absence of air.
