Question

Define cofficient of surface expansion. Write its S1 unit.​

Answer 1

Answer:

coefficient of thermal expansion… is the ratio of the fractional change in size of a material to its change in temperature. is represented by the symbol α (alpha) for solids and β (beta) for liquids. uses the SI unit inverse kelvin (K−1 or 1/K) or the equivalent acceptable.
