Studying cooling curves with a smartphone

Ramos Silva, Manuela ; Martín Ramos, Pablo (Universidad de Zaragoza) ; Pereira da Silva, Pedro

Resumen: This paper describes a simple procedure for the study of the cooling of a spherical body, using a standard thermometer and a smartphone. For a more thorough analysis of the data, a computer can also be used. Experiments making use of smartphone sensors have been described before, contributing to an improved teaching of Classical Mechanics1-11, but rarely expand to Thermodynamics12-14. In this experiment, instead of using a smartphone camera to slow down a fast movement, we are using the device to speed up a slow process. For that we propose the use of FrameLapse free app15 to take periodic pictures (in the form of a time-lapse video) and then of VidAnalysis Free app16 to track the position of the mercury inside the thermometer, thus effortlessly monitoring the temperature of a cooling body
