Summary
| Description |
Македонски: Опит кој прикажува ладење при испарување. Сондата на топломерот се става во етанол. Тој е на собна температура од 24,7 степени Целзиусови. Кога ќе се извади, етанолот кој се нафатил на сондата зема топлинска енергија од сондата за да испари. Поради тоа се намалува температурата на сондата. Извел: проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Demonstration of evaporative cooling. When the sensor is dipped in ethanol, the thermometer shows that it is with room temperature. When the sensor is taken out, the ethanol on the sensor takes heat energy from the sensor to evaporate, which causes decreasing of the temperature. Performed by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Expérience sur le refroidissement par évaporation.
Lorsque la sonde est trempée dans l'éthanol, le thermomètre montre que celui-ci est à la température de la pièce. Lorsque la sonde est sortie du liquide, l'éthanol restant sur celle-ci "utilise" la chaleur de cette dernière pour s'évaporer, ce qui amène une baisse de température de la sonde. Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine. Română: Demonstrație a răcirii prin evaporare. Când senzorul de temperatură este cufundat în etanol, termometrul arată că acesta este la temperatura camerei. După ce senzorul este scos, etanolul își trage căldură din senzor pentru a se evapora, ceea ce aparatul interpretează ca o scădere de temperatură. Efectuat de prof. Oliver Zajkov de la Institutul de Fizică al Universității Sfinții Chiril și Metodiu din Skopje, Macedonia. |
