For determining the volume of an irregularly shaped body when used in conjunction with a catch bucket. Suitable for density cylinders, sinkers and Archimedes principle devices.

For determining the volume of an irregularly shaped body when used in conjunction with a catch bucket. Suitable for density cylinders, sinkers and Archimedes principle devices. Made of galvanised steel sheet. The spout is properly angled to accurately measure displaced liquid. Hammer tone finished.

For determining the melting point of solid substances. (upper limit 250 degrees C) Consists of an aluminum cylinder (l x d), 50 x 63mm with a slanted hole of diameter 7mm on the top for inserting a thermometer. Can be heated on a burner. The substance to be melted is placed on the top of the cylinder. Melting point is noted when melting occurs.

For the qualitative study of expansion of liquids, the principles of thermometry, and the rise and fall of a liquid column due to expansion or contraction of air in a bulb. Consists of a borosilicate glass bulb of diameter approximately 50mm with a 30cm long stem of 5mm bore.

For demonstrating and determining the coefficient of volume expansion of liquids when heated. Consists of a borosilicate glass bulb to hold 10mL of a liquid, in a capillary stem with a funnel at the top. The capillary stem is graduated to 0.5mL, subdivided every 0.01mL.

To show that water has a maximum density at 4 degrees C. Consists of a sheet metal cylinder, with two tubes in the upper and lower regions for inserting thermometers through rubber stoppers. Mounted on a base and encircled midway by an outer trough for holding a mixture of ice and salt. Temperature of the water is measured at the top and bottom of the inner cylindrical vessel over a period as the water cools. Supplied without the thermometer.

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.

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 determining specific heat, heat of fusion and heat of vaporisation. Consists of two polished spun aluminum vessels, i.e. an inner calorimeter (h x d), 80 x 65mm and an outer calorimeter (h x d), 140 x 100mm. Includes a plastic ring for seating the inner calorimeter, a stirrer, and a plastic lid for outer vessel. The lid has two holes for the thermometer and the stirrer. Supplied without the thermometer.

To demonstrate unequal expansion in different metals on heating. Highlights the role of temperature and materials in practical applications such as in thermostats. Consists of a laminated strip of two different metals fitted in a wooden handle. The strip is about (l x w), 200 x 10mm. Due to differences in the co-efficients of linear expansion of both metals, the laminated strip bends dramatically on heating.

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 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 demonstrating the phenomenon of thermal convection in liquids caused by temperature variation. Consists of a rectangular shaped borosilicate glass tube (w x h), 15 x 21cm with a funnel shaped opening at the top for filling liquids. When this tube is partially filled with water and heated at one corner after adding a dye or potassium permanganate crystals or saw dust or aluminum powder, the movement of colors or particles illustrates the formation of convection currents.
