Question:
PLEASE EXPLAIN, WHAT IS LINEAR EXPANSION AND WHAT IS ITS DERIVATION,COEFFICENT OF LINEAR EXPANSION,AREAL EXPANSION,COFFIECENT OF AREAL EPANSION,CUBIAL EXPANSION AND COFFIENT OF
SAME
AND WHAT IS BETA, GAMMA,DELTA? RELATIONSHIP BETWEEN DELTA ,BETA ,GAMMA.
Answer:
Thermal Expansion
Over small temperature ranges, the linear nature of thermal expansion leads to expansion relationships for length, area, and volume in terms of the linear expansion coefficient .
AREAL EXPANSION
It is defined as α A = 1 A d A d T .
The relationship between the area and linear thermal expansion coefficient is given as α A = 2 α L .
The linear expansion coefficient, the area thermal expansion coefficient works as an approximation over a narrow temperature interval only.
CUBIAL EXPANSION
Coefficient of volumetric expansion is defined as increase in volume per unit original volume per Kelvin rise in temperature is called coefficient of volumetric expansion.
