EXPERIMENTAL VERIFICATION OF NEWTON'S LAW OF COOLING

Mjerenja su izvršena u praktikumu na Odjelu za fiziku u Osijeku. Za vrijeme mjerenja uvjeti u prostoriji su stalno bili kontrolirani. Jednim termometrom CATT2 uređaja je praćena temperatura tvari tijekom njezinog hlađenja, a drugim je praćena temperatura okoline. Pomoću teorijskog izraza za Newtonov zakon hlađenja dobivena je temperatura na koju bi se tijelo trebalo ohladiti u određenom vremenu te je grafički prikazana njezina usporedba s temperaturom dobivenom eksperimentom.Measurements were performed in a practicum at the Department of Physics in Osijek. During the measurement, the conditions in the room were constantly controlled. One thermometer of CATT 2 device measured the temperature of the substance during its cooling and the other one measured the ambient temperature. Theoretical expression for Newton's law of cooling was used to obtain the temperature at which the body should cool down in a certain time and its comparation with the temperature to which the body actually cooled down at that time is shown graphically
