Solids expansion tools used to investigate the thermal expansion of solids called muschen broek . In experiments conducted showed that nearly all solids when heated to change the length , area and volume .
a. length expansion
L = Lo { 1 + α ( t2 - t1 ) }
information
L = length after heating or cooling ( m ) or ( cm )
L o = initial length ( m ) or ( cm )
α = coefficient of expansion length ( / 0C )
t1 = initial temperature ( 0C )
t2 = final temperature ( 0C )
b . extensive expansion
A = Ao { 1 + β ( t2 - t1 ) }
information
A = area after heating or cooling ( m2 ) or ( cm2 )
Ao = initial area ( m2 ) or ( cm2 )
extensive expansion coefficient β = ( / 0C )
t1 = initial temperature ( 0C )
t2 = final temperature ( 0C )
note
α β = 2
c . volume expansion
V = Vo { 1 + γ ( t2 - t1 ) }
information
V = volume after heating or cooling ( m3 ) or ( cm3 )
Vo = initial volume ( m3 ) or ( cm3 )
γ = coefficient of volume expansion ( / 0C )
t1 = initial temperature ( 0C )
t2 = final temperature ( 0C )
note
γ = 3 α
