The apparatus shown in the figure consists of four glass columns connected by horizontal sections. The height of two central columns
B&C are
46cm each. The two outer columns
A&D are open to the atmosphere.
A&C are maintained at a temperature of
95oC while the columns
B&D are maintained at
5oC. The height of the liquid in
A&D measured from the base line are
58.8cm&51cm respectively. Determine the coefficient of thermal expansion of the liquid.
