    co2, there is not enough to radiate heat. it is also impossible for co2 to trap heat, there is not enough, and if co2 was ever a problem, we could use dry ice to cool the hot spots, dri ice is co2? odd, huh

    An oldy but a goody......

    One thing to keep in mind is that all non spontaneous processes in nature are proceeded by a spontaneous process...do I expect you to know what that means?

    Does this mean that if I point a flashlight at a cool object, the cool object is allowed to absorb the photons and then re-emit toward a warmer object?

    That statement by SSDD is pretty vacuous. He does not understand what spontaneous means in physics definitions .

    If you look up key words "luminescence spontaneous cold radiation" in Google you find lots of sites call it cold-body radiation or simply cold radiation.

    For example in wiki you will find this definition,
    Luminescence is spontaneous emission of light by a substance not resulting from heat; it is thus a form of cold-body radiation. ... This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating.

    This definition clearly shows that energy from a cold source can hit a warmer object. But when I posted this before, he simply went away.

    Spontaneous is defined in physics as: arising from internal forces or causes; independent of externalagencies; self-acting.

    Cold body radiation, or cold body radiation may be caused by chemical reactions, electrical energy, sub atomic motions or stress on a crystal...none of which can be deemed spontaneous...or self acting.

    Sorry guy...once more, you can't get around the second law.....only fools of the first order believe that they can...energy does not move spontaneously from a less ordered to a more ordered state.

    After an outside source, like a flashlight, adds energy to an object, the object is allowed to, spontaneously,
    emit photons toward warmer matter.

    Right?

    I know that you aren't the brightest bulb in the box, but even you should be bright enough to grasp that spontaneous, meaning no assistance from outside sources, means that once an OUTSIDE source adds energy to an object, spontaneity is no longer possible.

    That doesn't seem like such a hard concept to grasp even for borderline idiots such as yourself.

    If I add energy to an object, with my flashlight, the object can't spontaneously emit?

    Please explain then, how it does emit. Or explain that it doesn't.

    Wrong again. You always made up your own definitions in physics. That is another of your rewriting the terms of physics. No physicist agrees with your colloquial use of the word "spontaneous". Here is the definition of spontaneity that PHYSICISTS use"

    A spontaneous process is the time-evolution of a system in which it releases free energy and it moves to a lower, more thermodynamically stable energy state.

    Least you fly off the handle and say, "Energy is never free blah blah" The definition is talking about Gibbs free energy. It's a thermodynamic term, not another colloquial term you can redefine for your pleasure.

    Really SSDD; that is total bullshit. You are making things up again.

    Here is an example. When you shine a bright light on a phosphorescent material it stores energy in atomic excited states. That is NOT SPONTANEOUS. External work is being done on the system.

    When you remove the external light, the atoms emit light as they more slowly return to their ground states. That IS SPONTANEOUS because internal work is being output. That internal energy is called Gibbs Free Energy. See my previous post.

    Geez learn some thermodynamics. It's easy to look these things up if you know what to look for.

    luminescence (luminosity) - Memidex dictionary/thesaurus

    Luminescence
    emission of light by a substance not resulting from heat; it's thus a form of cold body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal. This distinguishes luminescence from incandescence.

    And the fact is wuwei, that you are the one who just makes shit up as necessary...like your comment HERE to Thresha91203 on the other thread claiming that spectroscopes don't measure the difference between input radiation and it's own internal radiation.... It measures the sum of those two...which doesn't even begin to describe how a spectroscope works. You regularly just make stuff up in an effort to make a point..or take information completely out of context....you are, in fact, a liar, imminently stupid, or both.
