The Joule's Calorimeter is a fully assembled unit comprising of heating coil, two mutually insulated aluminium beakers, a lid with rubber stopper with boreholes for thermometer and stirrer, and a heating coil. Innermost aluminium beaker has a capacity of 150 ml is used for determining the specific heat capacity of solids and liquids and for measuring the electrical heat equivalent.
The cover contains a mounted heating coil of approximately 2-3 ohms of resistance with standard fixing posts for electrical connections. When connected to a 6 volt power source (not supplied), this coil will cause a temperature rise of about 5 degrees centigrade in 10 minutes. The support posts and coil are coated to prevent electrolysis.
Lid fitted with 2 x 4mm socket heads.
This bundle set includes:
1 x Joule’s Calorimeter Assembly (Code: HL1080089)
1 x Density Cube Set - 7 Piece (Code: DENCUB7)
1 x Thermometer - General Purpose Immersion Lo-Tox: -20°C to +110°C x 0.5 (Code: GE4740-01)
1 × Measuring Cylinder - 100ml (Code: ARLW2063050-5)
Instructions included.
Also required (not supplied): Distilled water, apparatus to heat water (e.g. kettle, water bath), digital bench scales, 3 x leads with piggy back or stackable banana plugs on both ends (preferably red and black), ammeter, voltmeter and power supply (require 6V, max 1.7-2 Ohms) .
NOTE: A K-type thermocouple with probe & sensor can also be used in place of the thermometer, if preferred (sold separately).
