Simple Calorimeter to Measure Heat in Many Applications

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.
