If the coefficient of linear expansion of a material is high, the material will expand more for each degree rise in temperature

Unit of coefficient of linear expansion

Define the coefficient of linear expansion.

A thread of liquid is in a uniform capillary tube of length L. As measured by a ruler. The temperature of the tube and thread of liquid is raised by DeltaT . If gamma be the coefficient of volume expansion of the liquid and alpha be the coefficient of linear expansion of the material of the tube, then the increase DeltaL in the length of the thread, again measured by the ruler will be

A rod AB of length l is pivoted at an end A and freely rotated in a horizontal plane at an angular speed omega about a vertical axis passing through A. If coefficient of linear expansion of material of rod is alpha , find the percentage change in its angular velocity if temperature of system is incresed by DeltaT

The coefficient of linear expansion 'alpha ' of the material of a rod of length l_(0) varies with absolute temperature as alpha = aT -bT^(2) where a & b are constant. The linear expansion of the rod when heated from T_(1) to T_(2) = 2T_(1) is :-

A fluid having a thermal coefficient of volume expansion gamma is filled in a cylindrical vessel up to a height h_0 . The coefficient of linear thermal expansion of the material of the vessel is alpha . If the fluid is heated with the vessel , then find the level of liquid when temperature increases by Deltatheta .

A parallel plate capacitor of area A and separation d is provided with thin insulating spacers to keep its plates aligned in an environment of fluctuating temperature. If the coefficient of thermal expansion of material of the plate is alpha , find the coefficient of thernal expansion (alphas) of the spacers in order that the capacitance does not vary with temperature. (Ignore effect of the spacers on capacitance.)

An external presseure P is applied on a cube at 273K hence it compresses equally from all sides alpha is coefficient of linear expansion & K is bulk modulus of material. To bring cube to its original size by heating the temperature rise must be

In most reactions, the rate of reaction doubles or triples for ...... degree rise in temperature.
