THERMAL EXPANSIONS IN SOLIDS

DEFINATION:

"The expansion in solids is due to the absorption of heat is known as thermal expansion in solids"

Types:

1. linear thermal Expansion
2. Surface thermal Expansion
3. Volumetric thermal Expansion

LINEAR THERMAL EXPANSION:

"the expansions in either lenght or breadth or height of an isotropic solid due to the absorption of heat is known as the linear 

thermal expansion in solids"

SURFACE THERMAL EXPANSION:

"the expansion in the surface area of a solid due to the absorption of heat is known as surface thermal expansion in solids"

VOLUMETRIC THERMAL EXPANSION:

"The expansion in the volume of a solid due to absorption of heat is known as the volumetric thermal expansion in solids"
