    Hi, i am a bit confused of something-- if scientists believe that all matter contains tiny particles that are in constant motion, how can that be possible when an object example; a chair (which is matter) could possibly have particles that are in constant motion??
    any assistance would be kindly appreciated.
    thank you.

    The particles only move a very small distance and very fast. As the particles temperature approaches Absolute zero, motion almost ceases.

    The atoms are in constant motion, but on the scale of the whole chair it is not noticeable because, as Geo basically said, the motion is only over a very short distance: a distance on the atomic level, which is obviously not noticeable to us without equipment of some kind.

    This motion is where temperature comes from - the hotter something is, the greater the average kinetic energy of its particles, the colder it is, the lesser the kinetic energy of the particles.

    okay, so then even when the temperature changes in a room, so does the particles in a chair (in that same room)?
    thanks a lot!!

    'all matter contains tiny particles that are in constant motion'

    a very good concise explanation. Is it yours or did you quote someone?

    A very patronising, irrelevant post.

    Were you just being thoughtless, or do you like to stir shit?

    agreed





    Not sure if this question is answered or not so here's my fifty pence worth

    Yup, everything is in constant motion, the only exception is at absolute zero. Motion generates heat and vice versa, so anything at a temperature above AZ (-273 I think, or 0 kalvin) involves motion at an atomic level

    So yes, when you sit down billions of atoms are smashing against your buttocks



    Whats more mindboggling than a table moving is that a table is 99% not there!
    if an atom were the size of the eifel tower, all the mass of that atom equates to about the size of a golf ball, the rest is massless space.
    What makes that tiny amount of matter so much larger (so that your hand doesn't simply fall through the table) is the collossal forces holding the bits of matter together and apart, the inter-atomic forces are quite rediculous, they make neodymium magnets look like lego perspectively
    It's not how many questions you ask, but the answers you get - Booms

    YES YES YES when temp goes up atoms move faster !!!!!!! and the chair even expands a bit!!!
    (so it takes up more volume too, although unnoticeable!!!)

    I actually think he meant it, it is a very concise explanation. One gets a very different impression of his post imagining a sarcastic tone or an curious tone.

    thanks - I did mean it.

    It could be VERY sarcastic though! :P

    think of it as a metal chair:
    at room temperature it is solid, and all the particles are just vibrating, the distance is so small you can't see or feel it.

    If you increase the temperature the particles will move further apart as it melts and spread all over the floor.

    Heat it until it boils and the particles will completely break free and whizz around the room.

    So your chair could be moving, it is just a bit low in energy at the moment.

    In that case I apologise and I thank jakotaco for pointing out the alternative explanation.

    You have to think on an extremely small scale and a very large scale. it is a combination of chemistry and physics. the theory of relativity basicly states that motion is relative. so the chair itself is relative to your movement. i only say this to open your mind to the fact that movement is always happening. now the chair is made of an incomparable number of particles constantly in motion relative to the stability of their orbits. they move at such a small scale that u dont notice. like we dont notice that the earth is moving. motion is relative. avogadros theory states that one particle is made up of 6.22x10 to the 24th moles which gives you an idea of how small the particles are.
