Question

Define coefficient of linear expansivity

Answer 1

coefficient of linear expansion. [¦kō·ə′fish·ənt əv ′lin·ē·ər ik′span·shən] (thermodynamics) The increment of length of a solid in a unit of length for a rise in temperature of 1° at constant pressure. Also known as linear expansivity.

Answer 2

Answer:

The Coefficient of Linear Expansion can be defined as:

“The rate of change of unit length per unit degree change in temperature” Assuming the effect of pressure is negligible.

Metals: Coefficient of linear expansion \alpha _, at 20^, C (10^, K^)

Stainless steel: 10.1~17.3

Carbon steel: 10.8

Steel: 11.0~13.0
