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 Delta T. 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 Delta L in the length of the thread, again measured by the ruler will be

A wire is made by attaching two segments together end to end. One segment is made of aluminium and the other is steel. The effective coefficient of linear expansion of the two segment wire is 19 x 10^(-6)/C. The fraction length of aluminium is (linear coefficient of thermal expansion of aluminium and steel are 23 x 10^(-6).C and 12 x 10^(-6)/C, respectively )
