Question

what is cofficeint of superficial expanson

Answer 1

The amount by which unit area of a material increases when the temperature is raised by one degree is called the coefficient of superficial(i.e. area) expansion and is represented by β (Greek beta).If a material having an initial surface area A1 at temperature t1 and having acoefficient of superficial expansion β, ...Nov 28, 2015

Answer 2

the ratio of the increase of length, area, or volume of a body per degree rise in temperature to its length, area, or volume, respectively, at some specified temperature, commonly 0° C, the pressure being kept constant —called also expansivity
