Kuyini yokuthi liphansi futhi njengoba kulinganiswe

Sikhuluma nabo ngezinto inani lemithi ngendlela leli gama lisetshenziswa izifundo Science. Kusukela ubudlelwano bobukhulu kwamakhemikhali, i-physics kunikezwa kokucabangisisa ngale ndaba, kubalulekile ukwazi incazelo ezingokomzimba nenani, amayunithi abo, emkhakheni kwesicelo.

Isikhundla, definition, amayunithi

Ukwakheka kwezinto Okubaluleke ngokukhethekile kukhona ubudlelwane ambalwa. Ukwenza izibalo usebenzisa amanani ethize ngokuvumelana zibalo. Ukuze uqonde ukuthi inani ndaba kwamakhemikhali, sikunikeza incazelo kwethemu. Lena ubuningi ngokomzimba okuyinto ephawula inani amayunithi efanayo (ama-athomu, ion, ama-molecule electron) ekhona impahla. Ukuze siqonde ukuthi inani ndaba, siphawula ukuthi lesi silinganiso has ukuqokwa siqu. Ngo izibalo, lokusho ukusetshenziswa kwaleli nani, sebenzisa n incwadi. Amayunithi - Mol kmol mmol.

Inani

ibanga lesishiyagalombili angakawamukeli ukwazi ukuthi ukubhala chemical zibalo Angazi ukuthi inani ketshezi, indlela yokusebenzisa lesi silinganiso kulesi sibalo. Ngemva ukujwayelaniswa nge umthetho njalo isisindo izinto, kuba value ngokucacile leli ubuningi. Ngokwesibonelo, ekusabeleni hydrogen amandla omlilo-oksijini reactants lingemaphesenti kwamabili kuya kwelilodwa. Uma i-hydrogen is mass, okuyinto angena inqubo eyaziwa, kungenzeka ukunquma umoyampilo ezithathwe ingxenye ekusabeleni zamakhemikhali.

Isicelo amafomula ku enkompolo kunciphisa lihlela isilinganiso phakathi kwama reagents kokuqala, ukuze kube lula ukubala. Uyini umthamo ndaba kwamakhemikhali? Ngokuya izibalo, lokhu ezicini stereochemical ayifake equation. Okungukuthi, bajwayele ukuba afeze izibalo ezithile. Lokho kanjani ukubala izinhlayiya zishintshe kungelula, it is wajabulela Mol. Ukusebenzisa inombolo Avogadro sika, kungaba ibalwe ukuthi 1 imvukuzane kwanoma iyiphi reagent yakhiwa 6 × 1023 Mol ^-1.

Computing

Ingabe ufuna ukuqonda ukuthi yini yokuthi liphansi izinga? Ngo-physics, njengoba lesi silinganiso isetshenziswa. It edingekayo physics yamangqamuzana, lapho izibalo eyenziwa ingcindezi ivolumu gaseous kusukela equation Mendeleev-Clapeyron. Ukuze afeze kokusebenzisa izibalo ambalwa, kusebenza nomqondo mass izinyo lomhlathi.

Ngezansi kwakusho isisindo okuhambelana eyodwa imvukuzane of the chemical ethile. Ukuze sithole mass izinyo lomhlathi kungenzeka nge isihlobo mass-athomu (inani ukukhanya inani zama-athomu engqamuzana) noma ukuze uthole isisindo ngokusebenzisa into eyaziwa, lemali (Mol).

Ayikho umsebenzi inkambo esikoleni yokuthakwa kwamakhemikhali ezihlobene izibalo ezothando, ngeke akwenze ngaphandle ukusetshenziswa amazwi anjengokuthi "yokuthi liphansi". Oluphethe algorithm ungakwazi yini ukuyikhulisa kahle hhayi kuphela ngohlelo izibalo njalo, kodwa futhi nge eyinkimbinkimbi umncintiswano msebenzi. Ngaphandle kathisha ngesisindo izinto Kungenzeka ukuthi ingabe usebenzisa lo mqondo, ukwenza izibalo by ivolumu izinyo lomhlathi. Lokhu kuyiqiniso ezimweni lapho, ngekubambisana iqhaza izinto gaseous.
