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
