Question

Define the coefficients of linear expansion. Deduce relation between coefficients of linear expansion
and coefficient of superficial expansion.​

Answer 1

Explanation:

The ratio increase in length original length for 1 degree rise in temperature is called the coefficient of linear expansion, the ratio increase in area original area for 1 degree rise in temperature is called the coefficient of superficial expansion, and the ratio increase in volume original volume for 1 degree rise in ...

Answer 2

Answer:

The increase in dimensions takes place in all directions. We call the increase in length linear expansion, the increase in area superficial expansion, and the increase in volume cubical expansion. The ratio  for 1 degree rise in temperature is called the coefficient of linear expansion, the ratio  for 1 degree rise in temperature is called the coefficient of superficial expansion, and the ratio  for 1 degree rise in temperature is called the coefficient of cubical expansion.
