Nkhani yokhudza Zeroth Law of Thermodynamics
Mpaka pano, taona kokha momwe kutentha kumayenderana ndi zinthu ziwiri zomwe zakhudzana.
Kuti timvetse bwino lingaliro la kusinthasintha kwa kutentha, tiyeni tiwunikenso zinthu zitatu (tinene kuti zinthu A, chinthu B, ndi zinthu C). Mwachitsanzo, chinthu B ndi chinthu C sizimakhudzana, koma chinthu A chimakhudzana ndi chinthu B ndipo chinthu A chimakhudzana ndi chinthu C. Yang'anani chithunzi chili pansipa. Chifukwa chokhudzana ndi chilichonse kupatula chinthu A ndi chinthu B chili mu kusinthasintha kwa kutentha, momwemonso chinthu A ndi chinthu C zili mu kusinthasintha kwa kutentha. Kodi zinthu B ndi C zomwe sizimakhudzana nazo zili mu kusinthasintha kwa kutentha? Ngati tigwiritsa ntchito logic yokha, tinganene kuti chinthu B ndi chinthu C zilinso mu kusinthasintha kwa kutentha, ngakhale sizimakhudzana. Chinthu A ndi chinthu B zili mu kusinthasintha kwa kutentha, kutanthauza kutentha kwa chinthu A = kutentha kwa chinthu B.
Zinthu A ndi chinthu C zilinso mu kutentha koyenera, kutentha kwa chinthu A = kutentha kwa chinthu C. Chifukwa cha TA = TB ndi TA = TC, kenako TB = TCPopeza fizikisi siidalira pa logic yokha, imafunika kutsimikiziridwa kudzera mu zoyeserera. Kutengera zotsatira za zoyeserera, zapezeka kuti chinthu B ndi chinthu C zilinso mu thermal equilibrium. Pankhaniyi, kutentha kwa chinthu B = kutentha kwa chinthu C.
Ngakhale kuti chinthu B ndi chinthu C sizikugwirizana, koma chifukwa chakuti zikugwirizana ndi chinthu A, ndiye kuti chinthu B ndi chinthu C nazonso zili mu thermal equilibrium.
Choncho, ngati zinthu ziwiri zili mu mgwirizano wa kutentha ndi chinthu chachitatu, ndiye kuti zinthu zitatuzo zili mu mgwirizano wa kutentha wina ndi mnzake. Ili ndi Zeroth Law of Thermodynamics. Zeroth Law of Thermodynamics imafotokoza mfundo yogwirira ntchito ya thermometer, chipangizo choyezera kutentha. Kuwunikanso thermometer ya mercury kapena thermometer ya mowa. Mowa kapena mercury ikakhudzana ndi galasi ndi galasi ikakhudzana ndi zinthu zomwe kutentha kwake kumayesedwa, monga mpweya, madzi kapena thupi la munthu. Ngakhale kuti mercury siikhudzana ndi mpweya kapena madzi kapena thupi la munthu, chifukwa cha mercury ikakhudzana ndi galasi,
Pamene galasi ndi mpweya kapena madzi kapena thupi la munthu zili mu mgwirizano wa kutentha, mercury, ndi mpweya kapena madzi kapena thupi la munthu, nazonso zili mu mgwirizano wa kutentha.
Malamulo a fizikisi nthawi zambiri amayamba pa 1, nthawi zambiri amayamba pa 0. Amatchedwa lamulo la thermodynamic 1 chifukwa, pambuyo pa lamulo loyamba la thermodynamics, lamulo lachiwiri la thermodynamics ndi lamulo lachitatu la thermodynamics zitapangidwa, asayansi anazindikira kuti panali lamulo lofunika kwambiri lomwe silinapangidwe. Chifukwa chake, asayansi amatcha lamulo ili Zeroth Law of Thermodynamics.
