Question

In a vertical U-tube containing a liquid, the two arms are maintained at different temperature t subscript 1 end subscript and t subscript 2 end subscript. The liquid columns in the two arms have heights l subscript 1 end subscript and l subscript 2 end subscript respectively. The coefficient of volume expansion of the liquid is equal to

  1. fraction numerator l subscript 1 end subscript minus l subscript 2 end subscript over denominator l subscript 2 end subscript t subscript 1 end subscript minus l subscript 1 end subscript t subscript 2 end subscript end fraction    
  2. fraction numerator l subscript 1 end subscript minus l subscript 2 end subscript over denominator l subscript 1 end subscript t subscript 1 end subscript minus l subscript 2 end subscript t subscript 2 end subscript end fraction    
  3. fraction numerator l subscript 1 end subscript plus l subscript 2 end subscript over denominator l subscript 2 end subscript t subscript 1 end subscript plus l subscript 1 end subscript t subscript 2 end subscript end fraction    
  4. fraction numerator l subscript 1 end subscript plus l subscript 2 end subscript over denominator l subscript 1 end subscript t subscript 1 end subscript plus l subscript 2 end subscript t subscript 2 end subscript end fraction    

The correct answer is: fraction numerator l subscript 1 end subscript minus l subscript 2 end subscript over denominator l subscript 2 end subscript t subscript 1 end subscript minus l subscript 1 end subscript t subscript 2 end subscript end fraction
