Give the value of coefficient of volume expansion at $0\,^oC$ for ideal gas.
$\alpha_{\mathrm{V}}=3.3 \times 10^{-3} \mathrm{~K}^{-1}$
The volume of a gas at $20°C$ is $100 \,cm^3$ at normal pressure. If it is heated to $100°C$, its volume becomes $125\, cm^3$ at the same pressure, then volume coefficient of the gas at normal pressure is
A rod of length $2m$ rests on smooth horizontal floor. If the rod is heated from $0^o C$ to $20^o C$. Find the longitudinal strain developed? $(\alpha = 5 × 10^{-5}/^o C)$
The apparent coefficient of expansion of a liquid when heated in a copper vessel is $C$ and when heated in a silver vessel is $S$. If $A$ is the linear coefficient of expansion of copper, then the linear coefficient of expansion of silver is
A steel tape is calibrated at $20^{\circ} C$. On a cold day when the temperature is $-15^{\circ} C$, percentage error in the tape will be ……….. $\%$ $\left[\alpha_{\text {steel }}=1.2 \times 10^{-5}{ }^{\circ} C ^{-1}\right]$
Why the coefficient of volume expansion is zero for water at $4\,^oC$?
