Question

(b) Define coefficient of linear expansion. Give its Sl unit. State the factors on which
the thermal expansion of a solid depends​

Answer 1

Answer:

The coefficient of linear expansion can be mathematically written as:

αL=dLdT

S.I. Unit

The S.I unit is: ∘C−1orK−1

Explanation:

Expansion means, change or increase in length. If the change in length is along one dimension (length) over the volume, then it is called linear expansion. Here the reason behind the expansion is the change in temperature Thus, it is implied that the change in temperature will reflect in the rate of expansion. How much material can withstand its original shape and size under the influence of heat radiation is well explained using this concept.
