Often it is necessary in science to predict energy flow and even to measure this flow. Since energy is invisible, this often requires special equipment. Heat, a for of energy, is not measured directly. Instead, scientists must study heat by how it affects matter. Heat causes the molecules of matter to vibrate faster, which is recorded as temperature. With the Heat Transfer Kit, two insulated containers (called calorimeters), thermometers, and an aluminum transfer bar, make it possible to study the transfer of heat from a substance in one calorimeter to a substance in the other. The investigation measures the flow of heat as it s affected by different variables. Instructions are included!
