The length of a metallic rod is $5m$ at $0°C$ and becomes $ 5.01\, m$, on heating upto $100°C$. The linear expansion of the metal will be
$2.33 \times 10^{-5} {°C^{-1}}$
$6.0 \times 10^{-5} {°C^{-1}}$
$4.0 \times 10^{-5} {°C^{-1}}$
$2.0 \times 10^{-5}{°C^{-1}}$
If a bimetallic strip is heated, it will
A glass flask is filled up to a mark with $50\, cc$ of mercury at $18°C.$ If the flask and contents are heated to $38°C.$ ......... $cc$ mercury will be above the mark $?$ $(\alpha$ for glass is $ 9 × 10^{-6}{°}C^{-1}$ and coefficient of real expansion of mercury is $180 × 10^{-6}{°}C^{-1})$
Give the value of coefficient of volume expansion at $0\,^oC$ for ideal gas.
A steel tape $1 \;m$ long is correctly calibrated for a temperature of $27.0\,^{\circ} C .$ The length of a steel rod measured by this tape is found to be $63.0 \;cm$ on a hot day when the temperature is $45.0\,^{\circ} C .$ What is the actual length of the steel rod on that day ? What is the length of the same steel rod on a day when the temperature is $27.0\,^oC$? Coefficient of linear expansion of steel $=1.20 \times 10^{-5}\; K ^{-1}$
A pendulum clock keeps correct time at $0°C$. Its mean coefficient of linear expansions is $\alpha /^\circ C$, then the loss in seconds per day by the clock if the temperature rises by $t°C$ is
