On heating a liquid of coefficient of cubical expansion $ \gamma$ in a container having coefficient of linear expansion $ \gamma / 3$, the level of liquid in the container will
Rise
Fall
Will remain almost stationary
It is difficult to say
Why the density is changed of solid substances by increase in temperature ?
A thin walled cylindrical metal vessel of linear coefficient of expansion $10^{-3} $ $^o C^{-1}$ contains benzenr of volume expansion coefficient $10^{-3}$ $^o C^{-1}$. If the vessel and its contents are now heated by $10^o C,$ the pressure due to the liquid at the bottom.
If in winter season the surface temperature of lake is $1^{\circ} C$, the temperature at the bottom of lake will be ............
Write relation between coefficient of linear and volume expansion.
A rod of length $10\ meter$ at $0\,^oC$ having expansion coefficient $\alpha = (2x^2 + 1) \times 10^{-6}\,C^{-1}$ where $x$ is the distance from one end of rod. The length of rod at $10\,^oC$ is
