Thermal System Brass
Thermal System BrassThis new approach to measuring Specific Heat Capacity provides a self-contained apparatus to replace the traditional metal blocks and immersion heaters. A 300 g brass block (aluminium and steel also available) is mounted on an insulating base with a heating element attached to the underside. The block has a 4mm hole for data-logging probes, thermometer hole and felt insulating jacket. The heater is 30 W at 12 V and requires a standard laboratory power supply to provide up to 3 A. Typical temperature rises are 40˚C in 5 minutes providing a convenient investigation for students using thermometers and stopwatches as well as computer based data systems. Full instructions and theory included.
