       oC is the unit of Coefficient of Linear Expansion .

    Many materials, especially metals, physically expand when heated, due to the increased kinetic energy of the atoms. This expansion moves outward in all three dimensions, although not necessarily to the same degree. 

    The coefficient of linear expansion is the value that correlates the difference in length of an object to the difference in temperature of the object when the two length measurements were taken.

    A larger value means that the material expands more over a set temperature rise than a material with a lower coefficient
    Coefficients of linear expansion are represented by the Greek letter α (alpha) and are stated for ordinary room temperature.
