Isihloko mayelana noMthetho we-Zeroth we-Thermodynamics
Kuze kube manje, sibone kuphela ukulingana kokushisa okubonwa yizinto ezimbili ezithintanayo.
Ukuze siqonde umqondo wokulingana kokushisa ngokujulile, ake sibukeze izinto ezintathu (ake sithi izinto A, into B, kanye nezinto C). Isibonelo, into B kanye nento C azithintani, kodwa into A ithintana nento B kanti into A ithintana nento C. Buka isithombe esingezansi. Ngoba lapho ithintana nento ngayinye ngaphandle kwento A kanye nento B ku-equilibrium yokushisa, ngakho-ke into A kanye nento C ku-equilibrium yokushisa. Ingabe izinto B kanye no-C ezingathintani nazo zi-equilibrium yokushisa? Uma sisebenzisa i-logic kuphela, singasho ukuthi into B kanye nento C nazo zi-equilibrium yokushisa, yize zingathintani. Into A kanye nento B zi-equilibrium yokushisa, okusho ukuthi izinga lokushisa lento A = izinga lokushisa lento B.
Izinto A kanye nento C nazo zisesilinganisweni sokushisa, izinga lokushisa lento A = izinga lokushisa lento C. Ngenxa ye-TA =TB no-TA =TC, bese kuba u-TB =TCNjengoba i-physics ingathembeli nje kuphela ekucabangeni, idinga ukuqinisekiswa ngokusebenzisa izivivinyo. Ngokusekelwe emiphumeleni yokuhlolwa, kuvela ukuthi into B kanye nento C nazo zisesilinganisweni sokushisa. Kulokhu, izinga lokushisa lento B = izinga lokushisa lento C.
Ngakho-ke noma into B kanye nento C zingathintani, kodwa ngoba zithintana nento A, khona-ke into B kanye nento C nazo zisesilinganisweni sokushisa.
Ngakho-ke, uma izinto ezimbili zisesilinganisweni sokushisa nento yesithathu, khona-ke lezi zinto ezintathu zisesilinganisweni sokushisa komunye nomunye. Lona uMthetho we-Zeroth we-Thermodynamics. UMthetho we-Zeroth we-Thermodynamics uchaza isimiso sokusebenza se-thermometer, idivayisi yokulinganisa izinga lokushisa. Ukubuyekezwa kwe-thermometer ye-mercury noma i-thermometer yotshwala. Utshwala noma i-mercury ethinta ingilazi nengilazi ethinta izinto ezilinganiswa izinga lokushisa, njengomoya, amanzi noma umzimba womuntu. Nakuba i-mercury ingathintani nomoya noma amanzi noma umzimba womuntu, ngenxa ye-mercury ethinta ingilazi,
lapho ingilazi nomoya noma amanzi noma umzimba womuntu kusesilinganisweni sokushisa, i-mercury, kanye nomoya noma amanzi noma umzimba womuntu, nakho kusesilinganisweni sokushisa.
Imithetho yefiziksi ivame ukuqala ku-1, ayivamile ukuqala ku-zero. Ibizwa ngokuthi umthetho we-thermodynamic ongu-0 ngoba, ngemva komthetho woku-1 we-thermodynamics, umthetho wesibili we-thermodynamics kanye nomthetho wesithathu we-thermodynamics kwasungulwa, ososayensi baqaphela ukuthi kwakukhona umthetho oyisisekelo kakhulu owawungakakhiwa. Ngakho-ke, ososayensi babiza lokhu ngokuthi uMthetho we-Zeroth we-Thermodynamics.
