Question

A flask contains 100cc of a liquid at 10°c.when it is heated to 110°c increase in volume of the liquid appears to be 2cc.Find the coefficient of real expansion of the liquid.

Answer 1

The liquid monster gets 100 degrees, he runs away from the DEA. Unforutantly hattis whipped him!

Answer 2

Given :

Liquid of flask  V = 100 cc at 10°C .

Increase in volume of the liquid appears to be 2 cc when it is heated to 110°C .

To Find :

The coefficient of real expansion of the liquid.

Solution :

We know , increase in volume is given by :

$\Delta V=\alpha V \Delta T$

Here , $\alpha$ is  the coefficient of real expansion of the liquid.

$\alpha=\dfrac{\Delta V}{V\Delta T}\\\\\alpha=\dfrac{\Delta V}{V(T_f-T_i)}\\\alpha=\dfrac{2\ cm^2}{100\ cm^3\times (110-10)^oC}\\\\\alpha=2\times 10^{-4}\ {^oC}^{-1}$

Therefore , the coefficient of real expansion of the liquid is $2\times 10^{-4}\ {^oC}^{-1}$ .
