Question

.What is the relationship between coefficient of superficial expansion and co-
efficient of linear expansion?​

Answer 1

Answer:

Let l, b and A be the length, breadth, and area of the plate at temperature t °C. Consider superficial expansion of the plate area. Thus the coefficient of superficial expansion is twice the coefficient of linear expansion.

Answer 2

Answer:

the coefficient of superficial expansion is twice the coefficient of linear expansion.
