For demonstrating the phenomenon of convection in air and the principle of room ventilation.

Consists of an enamelled metal box (l x w x h), 20 x 10 x 10cm, having a sliding glass door and two glass chimneys. When a candle in a socket is placed under one chimney and a smouldering tape or touce paper is placed underneath the other chimney, the flow pattern of smoke dramatically illustrates the formation of convection currents. Candle, socket, tape or touce paper are not supplied.

For accurately measuring the coefficient of linear expansion of electrically conducting materials such as metal rods.

Consists of a frame of thermally rigid material consisting of two cast end pieces connected by two steel rods which appropriately hold a plated brass pipe (l x d), 500 x 25mm. The pipe acts as a steam jacket and is fitted with steam inlet and outlets as well as a tube suitable for inserting a thermometer through a rubber stopper. The pipe jacket is held in proper alignment with the help of two metal yokes, requiring minimal adjustment while removing or inserting the rod under study. One of the yokes has a knurled thumb screw to lock the steam jacket in place. The expanding rod makes contact with a 0.01mm micrometer which measures the extent of expansion when steam is passed through the jacket. The exact point of contact of the rod and the micrometer is found with the help of an indicator lamp. The design avoids use of loose wires.

Supplied with three rods of brass, copper and steel. Steam generator and thermometer are not included.

For preventing condensed water being carried over with steam prepared in a laboratory steam generator. Particularly useful when determining the heat of vaporisation with a steam calorimeter.

Consists of a borosilicate glass chamber with a curved inner tube to prevent drops of condensed steam from escaping, as well as a drainage tube.

For demonstrating the different heat conductivity of five metals by observing the melting of wax.

Consists of five rods (l x d), 75 x 5mm of aluminum, brass, iron, copper, and stainless steel which are radially fitted on a brass disk of about 27mm diameter. Each of these rods have a cavity at the outer end for holding paraffin wax. The central disk is joined to an insulated handle by 125mm long plated steel rod. Overall length about 32cm.

For demonstrating the expansion or contraction of metals.

Consists of two brass rods with insulated handles. One of the rods has a ring and the other one has a ball of approximate diameter 25mm, attached at the end. The brass ball passes through the ring when both are at room temperature, but when the ball is heated it expands and can not pass through the ring.

For determining the mechanical equivalent of heat by measuring the heat generated in an electrical resistance.

Includes the calorimeter set of two described above. The plastic lid is fitted with a heating coil to work with 6V supply or a battery, two 4mm socket binding posts for electrical connections, stirrer with an insulated handle and a single-hole rubber stopper for inserting a thermometer. Supplied without the thermometer. Requires a suitable voltmeter, ammeter, and thermometer (not supplied).

For showing that when different metal cylinders are heated to the same temperature and immersed individually in an equal quantity of water, the rise in temperature of the water is directly proportional to the specific heat of the chosen metal cylinder. Individual cylinders can also be used for precise specific heat determination.

Includes six cylinders made of aluminum, brass, copper, iron, lead, and zinc having diameters of 13mm. The length of each cylinder is adjusted so that all of them have the same mass.
