Question

The coefficient of thermal expansion of a material determines ____.

  1. The amount by which it bends on heating
  2. The amount by which it expands/contracts on changing temperature
  3. The pace at which it melts
  4. The pace at which it vaporizes

hintHint:

The coefficient of thermal expansion is a material property that is indicative of the extent to which a material expands upon heating.

The correct answer is: The amount by which it expands/contracts on changing temperature


    • The coefficient of thermal expansion (CTE) refers to the rate at which a material expands with increase in temperature. More specifically, this coefficient is determined at constant pressure and without a phase change, i.e. the material is expected to still be in its solid or fluid form.
