Resumo: We present the design of a relaxation calorimeter for specific heat measurements at room temperature directed to experimental physics teaching. We point out the characteristics of physical constitution and calorimeter operation and detail the computer programming involved. In the course of the experiment, monitoring the temperature and time of the specific heat measurements were made electronically in real time by a computer connected to an Arduino board. The data can be made available through tables and graphs through PLX-DAQ data acquisition tool and Excel spreadsheet. The results of the average specific heat obtained for iron, brass and lead samples, at room temperature, have small deviations in the order of about 3% when compared to literature values. The proposal uses low-cost and high-tech equipments aiming at innovation of teaching laboratories for science education or the development of experimental activities in instrumentation disciplines for teaching physics.

Apontamos as características de constituição física e de operação do calorímetro e detalhamos a programação computacional envolvida. No transcorrer da experiência, o monitoramento da temperatura e do tempo foi feito eletronicamente em tempo real por um computador conectado a uma placa Arduino. Os dados obtidos podem ser disponibilizados por de tabelas e gráficos através da ferramenta de aquisição de dados PLX-DAQ e a planilha Excel. Os resultados do calor específico médio obtidos para amostras de ferro, latão e chumbo, em temperatura ambiente, apresentam pequenos desvios da ordem de aproximadamente 3% quando comparados a valores da literatura. A proposta apresentada utiliza materiais de baixo custo e alta tecnologia objetivando a inovação dos laboratórios didáticos para ensino de ciências ou o desenvolvimento de atividades experimentais em componentes curriculares de instrumentação para ensino de Física.Imprensa Universitária - UFSC2017-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2017v34n1p27810.5007/2175-7941.2017v34n1p278Caderno Brasileiro de Ensino de Física; v. 34 n. 1 (2017); 278-2972175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2017v34n1p278/33987Copyright (c) 2017 Caderno Brasileiro de Ensino de Físicainfo:eu-repo/semantics/openAccessRocha, Fábio Saraiva daGuadagnini, Paulo HenriqueLucchese, Marcia Maria2017-12-20T09:39:28Zoai:periodicos.ufsc.br:article/45132Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2017-12-20T09:39:28Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
