Question

explain arieal expansion and derive expression for final area after heating coefficient of arieal expansion​

Answer 1

Answer:

Thermal expansion refers to a fractional change in size of a material in response to a change in temperature. This includes… changes in length compared to original length (∆ℓ/ℓ0) called linear expansion. changes in area compared to original area (∆A/A0) called areal expansion or superficial expansion.
