Question

Density of ice is $\rho$ and that of water is $\sigma$. What will be the decrease in volume when a mass M of ice melts

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Volume of ice = $\frac{M}{\rho }$, volume of water = $\frac{M}{\sigma }$

$\therefore$ Change in volume = $\frac{M}{\rho }-\frac{M}{\sigma }=M⟮\frac{1}{\rho }-\frac{1}{\sigma }⟯$
