Activities those can be performed with this kit mentioned below. 1. Temperature characteristic. 2. Differentiate between hot and cold objects. 3. To keep an object either hot or cold. 4. Thermal insulator materials. 5. Melting points of different objects. 6. State changing of objects.
Ring & Ball
A simple and economical device for demonstrating the thermal expansion of solids. Comprises an annular brass ring mounted on an insulated handle and a captive brass ball secured to the ring handle through a chain and having diameter just smaller than the ID or the ring. When cold, the ball easily passes through the ring but does not pass on heating. When heated to the same extent, the ball still passes through the ring showing the "expansion of a hole" effect. Sizes available are as below:
Ring & Ball (where ball is hanging with rod through a chain.)
Ring & Ball where ball is hanging with rod through a chain. Available in ball sizes as below:
Ring & Ball, Gravesande's
Similar to Ring & Ball, but both ball and ring mounted on separate insulated handles. Available in ball sizes as below:
Ring & Ball, Gravesand's, on Stand
Both ball and ring mounted on retort stand through a vertically adjustable collar, with ball suspended above the ring through a chain. Ball diameter 25mm. Mounted on stand, with ball suspended from adjustable rod
Ring & Ball, Gravesand's, on Stand (Another Type)
Both ball and ring mounted on retort stand through a vertically adjustable collar, with ball suspended above the ring through a chain. Ball diameter 25mm. Mounted on stand, with ball suspended from U-shaped bent rod, mounted on cast metal base
Bar & Gauge
For demonstrating expansion of solids by heating and contraction by cooling. Comprising a metal bar mounted on rod with insulated handle, and U-shaped metal gauge also mounted on insulated handle, with GO/NO GO hole. The space between both the arms precisely adjusted to just admit the bar length wise, and the bar cross-section will just pass through the hole, when cold or when both heated to the same extent. On heating the bar, neither its length nor cross-section will be admitted in the gauge at respective points. Bar and Gauge, with Bar size 110×10mm (length × diameter)

Thermal Expansion Bar
Shows the thermal expansion in solids. An L-shaped metal sheet is supported vertically on a plastic base, which carries a rectangular slot at the top along with a circular hole. The size of the slot and the diameter of the circular hole is just sufficient to permit accompanying metal rod to pass through it when cold. Heating the rod causes it to expand, which will then neither pass through the hole nor slot. Metal rod provided with insulated handle.
Lee's Thermal Apparatus
Apparatus made of brass mounted on a stand. Suspended with three strings attached to the lower plate from stout angular ring. Ring held on a heavy retort stand. Provision for inserting thermometer. Apparatus is used to determine relative conductivity of the poor conductors.
Bar Breaking Apparatus
To demonstrating the enormous forces which can be exerted during thermal expansion or contraction and are capable of breaking even the CI bars. Comprising a heavy cast metal frame with U-shaped slotted end pillar to carry a stout iron bar. The iron bar is threaded at one end for a large tensioning knob and has holes at the other end to accommodate the cast iron breaking bars.
Heat And Temperature Kit
Facilitate to understand the theoretical concepts of heat and temperature; students need not to arrange the different apparatus to perform the experiments. A single kit consists of all the necessary apparatus related to the experiments of heat and temperature with user instruction manual. After using this kit there is, no chance that any doubt will remain in the mind of students related to the heat and temperature.
Demonstrates the linear expansion of solids. Comprising two cast-metal uprights linked by a pair of parallel plated metal support rods and supporting an expansion bar at the top. The expansion bar is fixed to one upright and rests beneath a friction pointer on the other upright. The pointer moves along a scale reading 0 to 90°. Expansion of the bar on heating causes the pointer to move along the scale. Supplied complete with expansion bars, one each of aluminium, brass and iron.
Linear Expansion Apparatus, Simple
Demonstrates the linear expansion of solids and allows comparison of expansion rods of different materials. Comprises cast metal end supports mounted at each end of a horizontal metal reservoir, open at the top, that can take any liquid fuel such as alcohol. One of the end supports has a scale with pointer needle on the outside to indicate the expansion in the rod. Expansion rods supported in the holes near top of both the end supports and can be clamped at the end opposite to that of scale pointer. Burning of fuel in the reservoir causes rod at the top to expand, which in turn pushes the pointer needle showing deflection in the scale. Includes three expansion rods, 1 each of brass, copper and aluminum
Linear Expansion Apparatus, Micrometer Type, Economical
Two cast metal legs joined together by a pair of plated metal rods, with each leg having provision for horizontally supporting the ends of plated brass tube about 50cm long. The tube has a riffled nozzle near each end, facing opposite each other for use as inlet and outlet of steam, and another outlet at the center with holed rubber bung for inserting thermometer to measure the inside temperature. The test rod is inserted in the brass tube supported in rubber bungs at its each end. At one end is fitted a micrometer screw head reading to 0.01mm. A 4mm terminals provided on each leg for connecting an electric bell or galvanometer to indicate make/break of contacts. Supplied complete with 3 metal test rods, one each of copper, brass and steel.
Linear Expansion Apparatus, Gunther
Comprising two cast metal end pieces joined together by three nickel plated rods and carrying two sliding V-supports for a glass jacket with inlet and outlet tubes. One end piece fitted with spherometer reading 0.01mm, and other with contact screw. The glass jacket encloses both a brass and a copper rod each of about 50cm length, fitted through corks, a half turn of the jacket changing rod in contact with the spherometer. A thermometer can be attached to either of the rods by rubber bands. A binding post is fitted to each end piece for connecting an electric bell or galvanometer to indicate make/break of contacts. 1060200/1 Linear Expansion Apparatus, Gunther 1060200/2 Glass Tube, Spare, for Linear Expansion Apparatus, Gunther
Linear Expansion Apparatus, Micrometer Type
An improved version of Cat No. 1060180. Comprises of a plated metal tube having a riffled nozzles near each end, facing opposite each other for use as inlet and outlet of steam, and another outlet at the center with holed rubber bung for inserting thermometer to measure the inside temperature. Mounted horizontally on the metal base with the help of brackets with one end having a precision micrometer screw head reading to 0.01mm and other end having adjusting screw. The metal rod to be investigated is supported in the steam jacket by detachable conical cups situated at each end of the tube. The metal base painted with scratch-resistant epoxy coating. Supplied complete with one each, copper, brass and aluminium rods but WITHOUT thermometer.
Linear Expansion Apparatus, Precision, Dial Type
The accuracy in determination of coefficient of linear expansion of the material of a rod depends on the precision level of measurement of the expansion produced as a result of rise in its temperature, which is provided by a dial gauge indicator, graduated 0.01mm per division. Ideal for higher grade students. The apparatus is similar to Cat No. 1060220, in construction but has a dial gauge indicator instead of micrometer, which can be easily assembled into the apparatus or removed for convenient storage. It requires no electrical terminals or accessories for measurement. The apparatus comes completely assembled and includes four expansion rods, one each of steel, brass, aluminum, and copper.
Mechanical Equivalent of Heat Tube
Place a know mass lea shot into this l m tube and let it fall the length of the tube several times. Measure the rise in temperature of the short to calculate the heat produced. There should be a relation between the number of times you turn the tube over and the temperature of the shot. Heavy cardboard tube is 4cm in diameter and comes with 2 corks for the ends. Requires Lead Metal Shot and thermometer, not include.
