This cylindrical block-style calorimeter is made from mid steel and weighs 1 kg. It stands 3.5 inches tall with a diameter of 1.75 inches. The block is drilled with two holes: a large center hole with a 12.5 mm diameter for a special immersion heater, and a small hole with a 7.5 mm diameter for a thermometer or temperature sensor. The calorimeter is designed for the experimental determination of specific heat capacity of different metals. The two-hole configuration allows simultaneous heating and temperature measurement, making it a practical component for thermal physics experiments in educational settings.
