The steel petrol tank of a car is filled with $30$ litres of petrol at $10°\mathrm{C}$. If ${\alpha }_{\mathrm{steel}}$ is $24\times {10}^{-6} °{\mathrm{C}}^{-1}$ and ${\gamma }_{\mathrm{petrol}}$ is $9.9\times {10}^{-4} {}^{\circ }\mathrm{C}^{-1}$, the overflow of petrol at $40°\mathrm{C}$ is,

The densities of wood and benzene at $0°\mathrm{C}$ are $880 \mathrm{kg} {\mathrm{m}}^{-3}$ and $900 \mathrm{kg} {\mathrm{m}}^{-3}$, respectively. The coefficients of volume expansion are $1.2\times {10}^{-3} °{\mathrm{C}}^{-1}$ for wood and $1.5\times {10}^{-3} °{\mathrm{C}}^{-1}$ for benzene. At what temperature will a piece of wood just sink in benzene?

Volume expansion coefficient of a gas at constant pressure equal to:

A quality of a thermometer is that its heat capacity should be small. If $P$ is mercury thermometer, $Q$ is resistance thermometer and $R$ thermocouple type then

The temperature of equal masses of three different liquids $x, y$ and $z$ are $10°\mathrm{C}, 20°\mathrm{C}$ and $30°\mathrm{C}$ respectively. The temperature of mixture when $x$ is mixed with $y$ is $16°\mathrm{C}$ and that when $y$ is mixed with $z$ is $26°\mathrm{C}$. The temperature of mixture when $x$ and $z$ are mixed will be :
