Nickel plated copper calorimeter of 50 x 75 mm lagged and enclosed in an outer vessel of 75 x 100 mm size, with cover having terminals, a heating coil suitable for 3 – 6 V supply and holes for thermometer and stirrer.
With stirrer but without thermometer.
Copper calorimeter of 75 x 50 mm resting on felt pad inside wooden polished box provided with a brass nickel plated thermometer holder and copper stirrer.
Demonstrates the difference in thermal conductivity of two different materials.
The kit consists of two identical blocks, one made of aluminum and other made of plastic.
When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block it melts slowly.
The aluminum block has a larger heat capacity and a higher thermal conductivity while the plastic block has lower values of both parameters.
With instructions.
To determine the co-efficient of absolute expansion of mercury.
Glass tubes with vertical limbs contained within glass jackets approx.
460 x 25 mm height x diameter are closed by bungs and fitted with inlet and outlet tubes.
Upper ends of these vertical limbs are angled on emergence from the jackets to produce two short, adjacent limbs placed against a silvered glass scale 0 to 12 cm x 1 mm.
Mounted on stand 610 x 230 mm, height x width.
Overall height 750 mm approx.
supplied without mercury.
Polished aluminum container placed in an outer wooden case with thermometer, plastic top fitted with two terminals for heating coil and a hole for thermometer.
Copper calorimeter 75 x 50 mm with felt insulation, outer vessel of 100 x 65 mm size with a plastic lid having holes for thermometer and stirrer.
A thermometer holder is fixed to the outer vessel. Complete with stirrer.
To determine co-efficient of expansion of a gas at constant pressure.
A glass U-tube with a bulb and stopcock at one end, the other limb being open.
An outlet tube from the bottom of the U tube passes through a rubber bung and has a stopcock at the end.
The stem below the bulb is graduated 3 x 0.1 ml. An inlet tube with a mohr clip also passes through the bung.
A glass water jacket encloses the U tube.
All glass parts made of borosilicate glass requires only 20 ml mercury, which is not included.
Apparatus is fitted on heavy channel base, at one end of which is an adjusting screw, at the opposite end is a micrometer screw reading to 0.01 mm for measuring the expansion.
Supplied with one each of aluminium, brass and iron expansion rods but WITHOUT thermometer.
Consisting of metal rod 500 mm in length and 4.5 mm dia.
enclosed in a well - lagged, metal tube with three tubules for steam inlet, outlet and thermometer.
The metal rod to be investigated is supported in the steam jacket by detachable rubber bungs situated at each end of the tube.
