Amplitude of temperatures can be measured literally on everything - on liquid, solid substances, living organisms, air, gas. Hereinafter test substance for brevity we will call "object".
It is required to you
- - thermostat, for example, CLIMATELL 111, VMT;
- - test object;
- - paper;
- - handle.
Instruction
1. Place an object which amplitude of temperatures you should measure on a thermostat bottom. Depending on the object, the thermostat can be used not only what is offered above. Pick up the thermocase suitable for your requirements as at each of them the limited opportunities, at least on spaciousness. The main requirements what the thermocase has to possess is an opportunity to regulate and control temperature, availability of light and a possibility of observation of an object.
2. Hermetically close a thermostat cover.
3. For definition of the lower bound of amplitude - the lowest temperature at which the form and properties of substance or a living organism remain visually invariable gradually lower temperature. At the same time you monitor indications of the thermometer. As soon as at the last decrease the form or properties of an object visually changed, write down what was shown by the thermometer.
4. For continuation of experience return a cavity of the camera of the thermostat to room temperature.
5. Similarly define the top limit of amplitude. For this purpose gradually increase temperature in the thermocase camera. You look at an object and fix the maximum indication of the thermometer at which an object is invariable.
6. The limit between the first and second indications will also be amplitude of temperatures for a concrete object, with maintaining the concrete properties demanded it. For its calculation subtract from the greatest the indication the smallest.
