Question

Does the coefficient of linear expansion depend on length? Explain.
​

Answer 1

When something is heated or cooled, its length changes by an amount proportional to the original length and the change in temperature: The coefficient of linear expansion depends only on the material an object is made from.

The coefficient of linear expansion (thermal linear expansion) generally does not depend on length because it units are 1/K or 1/F (for imperial impaired) The actual expansion in terms of dT (temperature change) is L dT. ... It is a ratio of the change in length to length

Answer 2

Answer : No, Coefficient of linear expansion does not depend on length.

Explanation:

• When something is heated or cooled, its length changes by an amount proportional to the original length and the change in temperature: The coefficient of linear expansion depends only on the material an object is made from.

• The coefficient of linear expansion (thermal linear expansion) generally does not depend on length because it units are 1/K or 1/F . The actual expansion in terms of dT (temperature change) is LdT. It is a ratio of the change in length to length. The coefficient of linear expansion depends only on the material an object is made from.

Hence, Coefficient of linear expansion does not depend on length.
