Umthetho we-Zeroth wezinto ze-Thermodynamics
Kuze kube manje, sicabangele kuphela ukulingana kokushisa okubonwa izinto ezimbili ezithintanayo. Ukuze siqonde umqondo wokulingana kokushisa ngokujulile, ake sicabangele izinto ezintathu (ake sizibize ngokuthi into A, into B, kanye nento C). Isibonelo, izinto B no-C azithintani, kodwa into A ithintana nento B kanti into A ithintana nento C. Buka isithombe esingezansi.
Ngenxa yokuthi ziyathintana, izinto u-A no-B zisesilinganisweni sokushisa, futhi ngokufanayo izinto u-A no-C zisesilinganisweni sokushisa. Ingabe izinto u-B no-C, ezingathintani, nazo zisesilinganisweni sokushisa?
Uma sisebenzisa nje i-logic, singasho ukuthi into B kanye nento C nazo zisesilinganisweni sokushisa, yize zingathinti. Into A kanye nento B zisesilinganisweni sokushisa, okusho ukuthi shu into A = izinga lokushisa lento B. Izinto A kanye nento C nazo zisesilinganisweni sokushisa, izinga lokushisa lento A = izinga lokushisa lento C. Ngoba u-TA =TB kanye no-TA =TC, bese kuba u-TB =TC.
Njengoba i-physics inganciki kuphela ku-logic, idinga ukuqinisekiswa ngokusebenzisa izivivinyo. Ngokusekelwe emiphumeleni yokuhlolwa, kuvela ukuthi izinto u-B no-C nazo zisesilinganisweni sokushisa. Kulokhu, izinga lokushisa lento u-B = izinga lokushisa lento u-C. Ngakho-ke noma izinto u-B no-C zingathintani, ngoba zombili zithinta into u-A, izinto u-B no-C nazo zisesilinganisweni sokushisa. Lokhu kufingqiwe emgqeni omuhle olandelayo: Uma izinto ezimbili zikhonatibhalansi yokushisa nento yesithathu, bese izinto ezintathu zilinganatibhalansi yokushisa komunye nomunye.
Umthetho we-Zeroth we-thermodynamics chaza isimiso sokusebenza i-thermometer, ithuluzi lokulinganisa izinga lokushisa. Cabanga nge-thermometer ye-mercury noma i-thermometer yotshwala. Utshwala noma i-mercury ihlangana nengilazi, bese ingilazi ihlangana nento okulinganiswa izinga lokushisa kwayo, njengomoya, amanzi, noma umzimba womuntu. Nakuba i-mercury ingahlangani nomoya, amanzi, noma umzimba womuntu, ngoba i-mercury ihlangana nengilazi, lapho ingilazi nomoya, amanzi, noma umzimba womuntu kusesilinganisweni sokushisa, i-mercury nomoya, amanzi, noma umzimba womuntu nakho kusesilinganisweni sokushisa.
Imithetho yefiziksi ivame ukuqala ku-1, akuvamile ukuba ku-zero. Ibizwa ngokuthi umthetho we-zeroth we-thermodynamics ngoba ngemva kokuba imithetho yokuqala, eyesibili, neyesithathu ye-thermodynamics yakhiwe, ososayensi baqaphela ukuthi kukhona umthetho oyisisekelo owawungakakhiwa. Ngakho-ke, ososayensi babiza lo mthetho ngokuthi umthetho we-zeroth we-thermodynamics.
