    By the way- you want to drive the car all the time with the film? Could be detrimental to it if it's free in the package. The film could suffer scratching.

    The temperature is surly OK. But paper is hygroscopic so it would be wise to keep it in a dry, if cold, sealed box.
    Any way you look at it is OK with me.

    But that is the reverse of algebraic and thermodynamic convention.

    If you must keep film and paper in the trunk for extended periods, perhaps get one of the high-end coolers like the Yetti.
    I was going to suggest using a cooler. The Yeti seems to be an excellent solution.

    Personally, I would not store film and/or paper in a vehicle's trunk for the reasons already mentioned.

    Keeping paper dry is a must. I would say the same for film.

    Well it works if the absolute value is used, especially near absolute zero.

    The absolute value is an "operator" which is useful in mathematics for many special applications. But it is not very useful in this case.

    And I don't understand what you mean by how it works near absolute zero. Absolute zero is the null point on the Kelvin temperature scale where heat energy is zero... an unattainable condition in physical systems but, nevertheless, the point where the Kelvin temperature scale starts. Consequently, the Kelvin scale has no negative numbers.

    The Celsius scale is based on the triple-point of water assigned the value zero, which is 273.15 K. And that is the null point on the number line of the Celsius scale that our OP is referencing.

    The correct algebraic and thermodynamic concept is that -40 is a lower value than -15. That is related to their classic positions on the number line that goes from negative infinity (on the left) to positive infinity (on the right) in Cartesian coordinate systems.

    And the convention is that values increase when moving on the number line from left to right. And conversely, values decrease when moving from right to left.

    Just the way it is. And best not to reverse that for any one particular mental construct if one wants to stay true to the science.

    In this case the correct construct is to consider -40C to be a lower (heat) energy state than -15C... not a greater cold.

    Congratulations you broke the code!

    Absolute Zero is equal to 0 K and is equal to -273C and is equal to −459.67 F and is equal to 0R [Rankine] hence 0K exists.

    This is a reference to professorial jokes made in the first thermodynamics course.
    1. First Law: You cannot win.
    2. Second Law: Even though you cannot win, you must play.
    3. Third Law: Perfect conditions are reached at absolute zero or insanity, which ever comes first.


    Therefore using the second part of the third law, what I posted before makes perfect sense. Is that clear?

    Have a few drinks of Absolut and that should help clear things up for you.

    Re: Store film in car trunk

    I greatly appreciate you by your ideas.

    The car trunk is a good freezer but the humidity is a bad factor that I need to keep avoiding from my stuff. However, I have to take some of negatives and some prints for testing. Sometimes, testing is always the thing to do, but discussion is good for everyone who share their experience.

    I don't think the car trunk be warmed up under the sunshine in winter days, but it is cooler than inside the car (seat location) in summer days. I put the film and paper to cooler in summer.

    Thank you very much!
    Keep hearing from you.

    I keep Gin and Vodka in the freezer. It prevents ice poisoning.

    The triple point of Vienna standard ocean water, to be precise. Not just any old water.
