Ke Kānāwai Zero o nā Mea Thermodynamics
A hiki i kēia manawa, ua loiloi wale mākou ke kaulike wela ʻike ʻia e nā mea ʻelua e pili ana. No ka hoʻomaopopo hohonu ʻana i ke kumumanaʻo o ke kaulike wela, e noʻonoʻo kākou i ʻekolu mau mea (e kapa kākou iā lākou he mea A, mea B, a me mea C). No ka laʻana, ʻaʻole pili nā mea B a me nā mea C kekahi i kekahi, akā hoʻopā ka mea A i ka mea B a hoʻopā ka mea A i ka mea C. E nānā i ke kiʻi ma lalo.
Ma muli o ko lākou hoʻopā ʻana kekahi i kekahi, aia nā mea A a me B i ke kaulike wela, a pēlā nō hoʻi nā mea A a me C i ke kaulike wela. Aia anei nā mea B a me C, ʻaʻole e hoʻopā ana kekahi i kekahi, i ke kaulike wela?
Inā mākou e hoʻohana wale i ka logic, hiki iā mākou ke ʻōlelo aia pū ka mea B a me ka mea C i ke kaulike thermal, ʻoiai ʻaʻole lākou e pā. Aia ka mea A a me ka mea B i ke kaulike thermal, ʻo ia hoʻi ka wela ʻO ka mea A = ka mahana o ka mea B. Aia nā mea A a me ka mea C i ke kaulike wela, ʻo ka mahana o ka mea A = ka mahana o ka mea C. No ka mea, ʻo TA =TB a me TA =TC, a laila TB =TC.
ʻOiai ʻaʻole hilinaʻi wale ka physics i ka logic, pono e hōʻoia ʻia ma o nā hoʻokolohua. Ma muli o nā hopena o ka hoʻokolohua, ua ʻike ʻia aia nā mea B a me C i ke kaulike wela. I kēia hihia, ʻo ka mahana o ka mea B = ka mahana o ka mea C. No laila, ʻoiai ʻaʻole e hoʻopā ana nā mea B a me C kekahi i kekahi, no ka mea ua pili lāua ʻelua me ka mea A, aia nā mea B a me C i ke kaulike wela. Ua hōʻuluʻulu ʻia kēia ma ka laina nani aʻe: Inā pili nā mea ʻelua i ka hihiatke kaulike wela me kahi mea ʻekolu, a laila aia nā mea ʻekolu i ke kauliketke kaulike wela me kekahi.
Ke kānāwai zeroth o ka thermodynamics e wehewehe i ke kumumanaʻo hana ana wela, he mea ana wela. E noʻonoʻo i kahi ana wela mercury a i ʻole kahi ana wela waiʻona. Hoʻopili ka waiʻona a mercury paha me ke aniani, a hoʻopili ke aniani me ka mea e ana ʻia ana ka mahana, e like me ka ea, ka wai, a i ʻole ke kino kanaka. ʻOiai ʻaʻole hoʻopili ka mercury me ka ea, ka wai, a i ʻole ke kino kanaka, no ka mea, hoʻopili ka mercury me ke aniani, i ka wā e noho ai ke aniani a me ka ea, ka wai, a i ʻole ke kino kanaka i ke kaulike wela, aia pū ka mercury a me ka ea, ka wai, a i ʻole ke kino kanaka i ke kaulike wela.
Hoʻomaka pinepine nā kānāwai o ke kino ma ka 1, kākaʻikahi ma ka ʻole. Ua kapa ʻia ʻo ia ke kānāwai zero o ka thermodynamics no ka mea ma hope o ka hoʻokumu ʻia ʻana o nā kānāwai mua, ʻelua, a me ke kolu o ka thermodynamics, ua ʻike nā kānaka ʻepekema aia kekahi kānāwai kumu i hoʻokumu ʻole ʻia. No laila, kapa nā kānaka ʻepekema i kēia kānāwai ʻo ke kānāwai zero o ka thermodynamics.
