A metal ball immersed in alcohol weighs ${W_1}$ at $0°C$ and ${W_2}$ at $59°C.$ The coefficient of cubical expansion of the metal is less than that of alcohol. Assuming that the density of metal is large compared to that of alcohol, it can be shown that
${W_1} > {W_2}$
${W_1} = {W_2}$
${W_1} < {W_2}$
${W_2} = ({W_1}/2)$
The real coefficient of volume expansion of glycerine is $0.000597\, per°C$ and linear coefficient of expansion of glass is $0.000009\, per°C.$ Then the apparent volume coefficient of expansion of glycerine is
If a cylinder of diameter $1.0\, cm$ at $30°C$ is to be solid into a hole of diameter $0.9997\, cm$ in a steel plate at the same temperature, then minimum required rise in the temperature of the plate is ........ $^oC$ (Coefficient of linear expansion of steel $ = 12 \times {10^{ - 6}}°C^{-1}$)
At $NTP$ water boils at $100°C.$ Deep down the mine, water will boil at a temperature
Calculate the stress developed inside a tooth cavity filled with copper when hot tea at temperature of $57\,^oC$ is drunk. You can take body (tooth) temperature to be $37\,^oC$ and $\alpha = 1.7 \times 10^{-5}/^oC$, bulk modulus for copper $ = 140 \times 10^9\, N/m^2 $.
A rod of silver of $100\;cm$ is at $0^{\circ} C$ is heated to $100^{\circ} C$. Its length is increased by $0.19 \,cm .$ Coefficient of cubical expansion of the silver rod is
