Te Ine i te Pūngao Wera i roto i ngā Tauhohenga Matū
Pendahuluan
Ko te Calorimetry he peka pūtaiao e ako ana i te ine i ngā huringa o te pūngao wera i roto i ngā tauhohenga matū, i ngā tukanga ā-tinana rānei. Ko te kupu "calorimetry" i ahu mai i te kupu Latina "calor," ko te tikanga he wera, me te "metri," ko te tikanga he ine. Mā tēnei tikanga ka kitea he māramatanga nui ki te enthalpy, te entropy, me te kaha wera o ngā pūnaha rerekē. Ka arotakehia e tēnei tuhinga ngā ariā taketake o te calorimetry, ngā momo calorimeter, ō rātou mātāpono mahi, me ō rātou tono i roto i ngā mara rerekē pērā i te matū, te koiora, me te ahupūngao.
Ngā Ariā Taketake o te Calorimetry
Ko te tikanga, ko te ine i te pāmahana e puta ana ina whakaranua, ina tauhohe rānei ngā matū e rua.
