Question
In a vertical U-tube containing a liquid, the two arms are maintained at different temperatures 
and 
. The liquid columns in the two arms have heights 
and 
respectively. The coefficient of volume expansion of the liquid is equal to
The correct answer is:
Suppose, height of liquid in each arm before rising the temperature is l.
With temperature rise height of liquid in each arm increases i.e. l1 > l and l2 > l
