The Wonders of Energy: Why isn't "cold" a thing? How do other compounds, mixtures, and materials make something 'colder' like glycol? By: Ian Davis -------------------------------------------------------------------------------------------------------------------------------- Introduction: I'm sad to ruin your childhood, but 'cold' is just a term, and not really a thing in and of itself. I used to thing that 'cold' was just tiny particles shaped like little snowflakes that would make something cooler, however, as soon as I got into middle school, I learned that 'cold' is just the absence of heat. Now I love knowing the "ins-and-outs" of this little definition (including thermal equilibrium don't worry) but nevertheless always had questions about one particular thing, how do certain compounds, mixtures, and materials make something 'colder' and why is that their natural property? We are used to understanding that if
