Two vertical glass tubes filled with a liquid are connected at their lower ends by a horizontal capillary tube. One tube is surrounded by a bath containing ice and water at 0°C and the other by hot water at t°C. The difference in the height of the liquid in the two columns is Δ h, and the height of the column at 0°C is h 0 . Coefficient of volume expansion of the liquid is.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In equilibrium,
Pressure at A = Pressure at B
h 0 ρ 0 g = (h 0 + Δ h) 
⇒ γ =
