Experiments making use of smartphone sensors have been described before, contributing to an improved teaching of classical mechanics, but rarely expand to thermodynamics. 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 the free app Framelapse to take periodic pictures (in the form of a time-lapse video) and then the free app VidAnalysis to track the position of the mercury inside the thermometer, thus effortlessly tracking the temperature of a cooling body (Fig. 1).<\/jats:p>","DOI":"10.1119\/1.5018696","type":"journal-article","created":{"date-parts":[[2017,12,27]],"date-time":"2017-12-27T21:17:08Z","timestamp":1514409428000},"page":"53-55","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":13,"title":["Studying cooling curves with a smartphone"],"prefix":"10.1119","volume":"56","author":[{"given":"Manuela Ramos","family":"Silva","sequence":"first","affiliation":[{"name":"CFisUC, Department of Physics, FCTUC, Universidade de Coimbra 1 , P-3004-516 Coimbra, Portugal ; manuela@uc.pt"}]},{"given":"Pablo","family":"Mart\u00edn-Ramos","sequence":"additional","affiliation":[{"name":"CFisUC, Department of Physics, FCTUC, Universidade de Coimbra 2 , P-3004-516 Coimbra, Portugal"},{"name":"EPS, Universidad de Zaragoza 3 , Ctra.
