Question

What is expansion of SL unit

Answer 1

Answer:

We know the definition of the areal expansion coefficient: α=1AdAdT. Doing unit analysis (in any system with L being a length, Θ being a temperature), [α]=1[A]⋅[A][T]=L2L2⋅Θ=Θ−1. Since the SI unit for temperature is Kelvin, the unit for the areal expansion coefficient is K−1 .
