-
The device, which is rotated around its axis by a centrifuge machine, shows how the work can be changed into heat and how this last one is a form of energy. -
The device, made of two boxwood moulds with lenticular cavities, shows how the phenomenon of reicing depend on the influence provoked by pressure on the solidification process. Reicing is the phenomenon which shows how glaciers are shaped depending on the surrounding landscape. -
Ingenhousz’s apparatus allows the comparison between the thermic conductivity coefficients of several materials. -
The device permits the exsperimental test concerning the anomalous behaviour oh the water in the temperature interval between 4°C and 0°C. -
The instrument is used to classify the materials which are good or bad conductors of heat. -
The apparatus is used to show the noteworthy intensity of the contraction forces, which are elastic forces generated in the solids because of, for example, a fall in the temperature. -
A blowpipe with suitable joint to be fixed to an oxyhydrogen lamp, for the purpose of heating to the limit of incandescence, the lime burner of the lamp itself. Starting from the 1950’s the lime lamp was used as a projector, substituting the electric arc, which was improved by H. Davy in 1908. -
Electric appliance used as a heater in calorimetry tests. -
A vapour pressure thermoscope. The instrument permits to display, through the heat of the hand, the effects of pressure caused by the vapour of a liquid contained in a vacuum pipe. -
The instrument is a mercury thermometer with spherical bulb that allows to find variations of saturated steam’s tension in function of temperature. -
Water calorimeter with a wooden insulating base. -
Calorimeter on a walnut tablet. -
The Dewar vase (James Dewar, 1842–1923), commonly known as “thermos” because of its characteristics of thermic insulator, is used to preserve heat or cold in a liquid body. -
The criophore allows to study water evaporation in a very rarefied atmosphere. -
The device can be used to show the heat different absorption depending on the colour of the sides of the cube. -
Alcohol stove used as a heater and, in particular, to melt sealing-wax. -
A couple of gas burners, made of refractory material. -
A glass alcohol stove with a cover to put the fire off; the wick is missing. The device is used as a heater in science labs. -
A metal and glass alcohol lamp with a flame regulator. -
Bunsen lamps, with one or more ways, are burners for lighting gas, used as heaters in science labs. The name of the burner comes from the one of the German chemist Ropbert Wilhem von Bunsen (Gottinga 30-3-1811- Heidelberg 16-8-1899). -
Exsamples of simple Bunsen lamps. -
The metal appliance is made of a horizontal hollow bar connected with the gas distributor; four Bunsen burners all alike are tightened to the bar at the same distance. -
An alcohol security lamp, largely used in mines, because it permits to find out the presence of grisou, a highly inflammable gas. -
A kind of oil lamp dating to the end of the 19th century, made of brass and Vienna crystal. -
A model of a hot air engine which allows to analyse how a motive power is generated by means of the burning of coal and similar fuels. -
An appliance used to show the expansion of metallic rods at increasing temperatures. The project and construction of the first appliances of this kind date back to the early 18th century. -
The device allows to show thermo-luminous radiations, even very weak ones, which hit it and make the whirl in the centre of the ampoule rotate. -
The model allows to analyse the parts making up a thermic engine. It includes the cylinder and a section of the appliance which distributes the steam, the transforming organs and the organs regulating motion. -
The wooden model represents a section of steam distribution appliance of a thermic engine. -
Liquid thermometer. Temperature is normally measured according to the centigrade scale which was discovered by the Swedish scientist Celsius in 1742. -
-
The instrument is mounted on an iron thin tablet. On the tablet there are two scales, “Centigrade e Reamur”, situated symmetrically to the capillary of the thermometer. -
A thermometer used to measure variations of temperature through a different expansion of three metals. -
A thermometer which is suitable to measure the maximum and minimum temperature in a single physical place, in such a way as to show the thermic range to which the place is subjected. -
Example of maximum and minimum temperature thermometer -
This instrument, which has been invented by the Scottish physician Leslie at the beginning of the 19th century, is an air thermometer; it allows to measure the difference in temperature between two near places. It can also be used to show the absorption of radiating warmth. For such a purpose, one of the two bulbs is covered by a layer of lamp-black, so that it can absorb all the radiations. -
An instrument whose working is based on the phenomenon of expansion of solids. -
The instrument is an example of maximum and minimum temperature thermometer. It was invented by the English scientist James Six (1731-1793) towards the end of the 18th century and it was improved by Angelo Bellani (1736-1852) who gave it the name “thermometrographer”, just to put in evidence that this kind of thermometer can give measures without the continuous presence of an observer. -
The instrument is an example of thermometrographer. -
The instrument, which is characterized by a high sensibility, permits to register very small variations of temperature. Its invention, that dates back to the one of Leslie’s differential thermometer, is due to the American Rumford (Woburn 1753-Paris 1814) -
Rumford’s thermoscope belonging to an earlier period. -
The device allows the study of the behaviour of a liquid in particular conditions of temperature and pressure.
