Perea Martins, J E M [UNESP]2022-04-282022-04-282020-03-01Physics Education, v. 57, n. 2, 2020.1361-65520031-9120http://hdl.handle.net/11449/223206This work presents the design of an inexpensive electronic system to measure water temperature and generate an experimental data set used to verify the fitting between experimental and theoretical curves of a water-cooling process. The cooling constant is computed with three different theoretical methods to check their efficiency and this approach allows the association of theoretical and experimental aspects of physics, mathematics and electronic instrumentation, which can motivate interesting discussions in the classroom.engArtigo10.1088/1361-6552/ac3b962-s2.0-85122520184
