3B Scientific, UE2030400-115, Experiment for Heat: Internal Energy and Electrical Work, 115 V, 50/60 HzUE2030400-115 Includes Only:Copper CalorimeterAluminium CalorimeterTemperature SensorPair of Adapter Cables with 4 mm Safety Plugs/2 mm PlugsPair of Safety Experiment Leads, 75 cm, blue, redDigital Multimeter P1035DC Power Supply 20 V, 5 A (115 V, 50/60 Hz)Features:Objective: Increase internal energy by means of electrical workThis experiment investigates how the internal energy of copper and aluminium calorimeters can be increased by electrical work. As long as the aggregate state does not change and no chemical reactions occur, it is possible to determine the increase in internal energy from the rise in temperature to which it is proportional. In order to prevent heat being transferred from the calorimeters to their surroundings, the series of measurements should start at a temperature somewhat below the ambient temperature and finish at a temperature only slightly above that of the surroundings.
