CALORIMETER, JOULE'S, IN WOOOEN BOX 100 x 75mm (0243)
Calorimeter vessel comprising of a nickel-plated copper calorimeter, placed inside a polished wooden box surrounded with felt to minimize the heat loss. The vessel is covered at I the top with a bakelite cover which has a resistance coil mounted at the underside that terminates in binding posts on the upper side for electrical connections. The bakelite cover also has a slit for stirrer and a hole for suspending thermometer through a rod clamp arrangement on the wooden box. Supplied complete with stirrer but without thermometer.

CALORIMETER, JOULE'S, DOUBLE WALL, COPPER (0244)
Provides more accurate results. Comprises a smaller inner nickel plated copper calorimeter vessel 75x50mm [height x diameter), enclosed in an outer vessel 100x75mm [height x diameter) with felt lagging in between them for minimizing heat loss. A close fitting bakelite lid is provided with a resistance coil mounted at the underside so as to be positioned sufficiently inside inner vessel and a pair of 4mm terminals at the top for electrical connections. The lid has provision for thermometer and stirrer. The resistance coil has recommended working current of 0.5A with a maximum of 1 A to minimize the local boiling of liquid. Supplied complete with stirrer but without thermometer.

SET OF SPECIFIC HEAT CYLINDERS, EQUAL IN MASS (0247)
Comprising six cylinders of diameter about 16mm, with weight of each cylinder adjusted to 100g. Includes one cylinder each of copper, lead, brass, zinc, iron and aluminium. Cylinders vary in length from 5cm to 19cm to get the same mass and are drilled across cross-section near one end for suspension. Metal cylinders rest in the cylindrical recesses drilled in a wooden block. Metal identification stamped on each cylinder. Can also be used in specific gravity / density experiments to compare their relative densities.

SET OF SPECIFIC HEAT CYLINDERS, EQUAL IN SIZE (0248)
Comprising six cylinders of same size but of different mass and specific heats, one each of copper, lead, brass, zinc, iron, and aluminium. Size of each cylinder about 38 x 9.5mm (height x diameterJ. Useful for comparing the specific heats of their materials. Metal cylinders rest in the cylindrical recesses drilled in a wooden block. Metal identification stamped on each cylinder. Can also be used in specific gravity/density experiments to compare their relative densities.

VENTILATION APPARATUS (0249)
Demonstrates the convection currents in air. Comprises a sheet metal box with open sliding glass front and two circular openings at the top for mounting glass chimneys. On the inner side, below each chimney, a candle holder is mounted. Air heated by a candle placed beneath one of the chimneys with glass door closed, causes the flow of convection currents, which can be observed by bringing a smoldering string near the top of other unheated chimney. Supplied without candles

LESLIE'S CUBE (0250)
Useful for qualitative experiments in thermal radiation. The results can also be quantified using a suitable radiation sensor facilitating investigation of radiation from different surfaces at a single temperature or radiation from a single surface at different temperatures [Stefan-Boltzman's Law). Comprises a sheet metal cube of sides about 130mm with opening at the top, for pouring in water and inserting a thermometer through a holed rubber stopper. One each of the four vertical faces is finished black, varnished, roughened and polished.
