Chinyorwa pamusoro peMutemo weZeroth weThermodynamics
Kusvika pari zvino, tangoona chete kuenzana kwekupisa kunoitika pazvinhu zviviri zviri kusangana.
Kuti tinzwisise pfungwa ye thermal equilibrium zvakadzama, ngationgororei zvinhu zvitatu (ngatitii zvinhu A, chinhu B, uye zvinhu C). Semuenzaniso, chinhu B nechinhu C hazvibatane, asi chinhu A chinosangana nechinhu B uye chinhu A chinosangana nechinhu C. Tarisa mufananidzo uri pazasi. Nekuti kana zvakabatana nechimwe nechimwe kunze kwechinhu A nechinhu B zviri mu thermal equilibrium, saka chinhu A nechinhu C zviri mu thermal equilibrium. Zvinhu B neC zvisingabatane zviri mu thermal equilibrium here? Kana tikashandisa logic chete, tinogona kutaura kuti chinhu B nechinhu C zviri mu thermal equilibrium, kunyangwe zvisiri mu thermal equilibrium. Chinhu A nechinhu B zviri mu thermal equilibrium, zvichireva kuti tembiricha yechinhu A = tembiricha yechinhu B.
Zvinhu A nechinhu C zviriwo mu thermal equilibrium, tembiricha yechinhu A = tembiricha yechinhu C. Nekuda kweTA =TB uye TA =TC, wobva wati TB =TC. Sezvo fizikisi isingangovimbi nepfungwa chete, inofanira kuratidzwa kuburikidza nekuyedza. Zvichibva pamhedzisiro yekuyedza, zvinoonekwa kuti chinhu B nechinhu C zviriwo mukuenzanisa kwekupisa. Muchiitiko ichi, tembiricha yechinhu B = tembiricha yechinhu C.
Saka kunyangwe chinhu B nechinhu C zvisiri kubatana, asi nekuti zviri kubatana nechinhu A, saka chinhu B nechinhu C zviriwo mu thermal equilibrium.
Saka, kana zvinhu zviviri zviri mu thermal equilibrium nechinhu chechitatu, saka zvinhu zvitatu zviri mu thermal equilibrium pamwe chete. Uyu ndiwo Zeroth Law weThermodynamics. Zeroth Law weThermodynamics inotsanangura mashandiro e thermometer, mudziyo wekuyera tembiricha. Kuongororwa kwe mercury thermometer kana alcohol thermometer. Doro kana mercury iri mu girazi negirazi iri mu divi rezvinhu zvine tembiricha inoyerwa, zvakaita semhepo, mvura kana muviri wemunhu. Kunyangwe mercury isiri mu divi remhepo kana mvura kana muviri wemunhu, nekuda kwe mercury iri mu divi regirazi,
kana girazi nemhepo kana mvura kana muviri wemunhu zviri muchiyero chekupisa, mercury, uye mhepo kana mvura kana muviri wemunhu, zviriwo muchiyero chekupisa.
Mitemo yefizikisi inowanzo tangira pa1, kashoma kutanga pazero. Inonzi mutemo wethermodynamic 0 nekuti, mushure memutemo wekutanga wethermodynamics, mutemo wechipiri wethermodynamics nemutemo wechitatu wethermodynamics zvagadzirwa, masayendisiti akaona kuti paive nemutemo wakakosha wakanga usati wagadzirwa. Nokudaro, masayendisiti vanodana uyu kuti Mutemo weZeroth weThermodynamics.
