Coefficient of real expansion of mercury is $ 0.18 \times 10^{-3}{°C^{-1}}$. If the density of mercury at $0°C$ is $13.6\, gm/cc$. its density at $473K$ is
$13.11\, gm/cc$
$26.22 \,gm/cc$
$52.11\, gm/cc$
None of these
What will happen if a rod is tied with fixed supports rigidly at both ends and temperature is increased ?
A steel tape gives correct measurement at $20^o C$. A piece of wood is being measured with the steel tape at $0^o C$. The reading is $25 \,\,cm$ on the tape, the real length of the given piece of wood must be:
Show that the coefficient of area expansion, $(\Delta A / A) / \Delta T,$ of a rectangular sheet of the solid is twice its Iinear expansivity, $\alpha_{1}$
A bimetallic strip consists of metals $A$ and $B$. It is mounted rigidly as shown. The metal $A$ has higher coefficient of expansion compared to that of metal $B$. When the bimetallic strip is placed in a cold both, it will :
Thermal expansion of a solid is due to the
