Question

Coefficient of volume expansion of mercury is 0.18 x ${10}^{-3}{/}^o$C. If the density of mercury at $0^o$C is 13.6 g/cc then its density at ${200}^o$C is

• A. 13.11 g/cc
• B. 52.11 g/cc
• C. 16.11 g/cc
• D. 26.11 g/cc

Answer 1

The correct option is A 13.11 g/cc

Co-efficient of volume expansion of

Density of mg at

To find :

Density at

We Know

$\rho =\frac{{\rho }_0}{(1+r_{0}t)}$

Where

$\rho$ $\to$ Density at any temp other than $0^{\circ }C$

$\rho$ $\to$ Density at $0^{\circ }C$

$r_0$$\to$ co-efficient of volume expansion.

$t$$\to$

temp at which density is to be calculated.

$\rho =\frac{13.6}{1+0.18\times 200}$

$=\frac{13.6}{1.036}$

$=13.11g/cc$
