What is the length of a rod at 65 degrees c if its length at 15 degrees c is 1.2 meters?

Answer by  nrw24 (53)

The answer to this question would rely on the material that the rod is made out of. Materials have a value known as the 'Coefficient of Thermal Expansion', which is a unique value that describes their volumetric change with temperature. From the volumetric change, dimensional change can be calculated.

There is not enough information to answer this question. The answer depends on the coefficient of thermal expansion for the material the rod is made. Thus, the answer depends on what material the rod is made of. As an example, an aluminum rod would expand much more than a steel rod which would expand much more than a ceramic rod.
