Linear Thermal Expansion of Solids: When the temperature of a solid changed ΔT, the change of its length ΔL is very nearly proportional to its initial length multiplied by ΔT. The Linear Expansion equation is:
  ΔL = αL0ΔT
Where:
α: the Coefficient of linear expansion
L0: Initial length of the object
ΔL: Length change of the object
ΔT: Temperature change of the object

Area Thermal Expansion: When the temperature of a surface changed ΔT, the change of its area ΔA is very nearly proportional to its initial area multiplied by ΔT. The Area Expansion equation is:
  ΔA = γA0ΔT
Where:
γ: the Coefficient of Area expansion
A0: Initial area of the object
ΔA: Area change of the object
ΔT: Temperature change of the object

Volume Thermal Expansion: When the temperature of a volume changed ΔT, the change of its volume ΔV is very nearly proportional to its initial volume multiplied by ΔT. The Volume Expansion equation is:
  ΔV = βV0ΔT
Where:
β: the Coefficient of volume expansion
V0: Initial volume of the object
ΔV: Volume change of the object
ΔT: Temperature change of the object
