Question

In an experiment to find coefficient of real expansion of a liquid , 70 cm column of liquid at 0^oC is found to balance 71.26 cm column of liquid at 100^oC, $γ$ _R of that liquid is

Moderate

A

180 x 10^-6/⁰C
B

80 x 10^-6/⁰C
C

90 x 10^-6/⁰C
D

126 x 10^-6/⁰C

Solution

$γ_{r} = \frac{v_{2} - v_{1}}{v_{1} Δ t}$
