The apparatus shown in figure consists of four glass columns connected by horizontal sections.The heights of two central columns B and C are 49 cm each. The two outer column A and D are open to atmosphere. A and C are maintained a a temperature of 95 degree C, while column B and D are maintained at 5 degree C. The heights of liquid in A and D measured from base line are 52.8 cm and 51 cm respectively. Determine the coefficient of thermal expansion of the liquid.

As the liquid columns in the glass tubes are in equilibrium:
Pressure diffference between the columns A and B = Pressure difference between the columns C and D
