What is the relative density of liquid if the height of the water coloumn and the height of a liquid column in a Hare's apparatus are 20 cm and 40 cm, respectively ?

What would you conclude if the heights of both liquids in a Hare's apparatus are equal ?

Write the formula for height of liquid column in capillary .

When water is used as barometer liquid the height of the water column at sea level is 76 cm.

The formula for height of a liquid column (h) in a capillary tube is

If the relative density of a liquid is 1, What do you mean by relative density?

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