Laba bobathathu zithi ndaba:

Omunye futhi unesimo esifana kungavuka nemvelo ezintathu uthi - ngesimo igesi, liquid okuqinile. Ngakho, uma ucezu ice ukuxoxa, lincibilike bese ephenduka ibe amanzi; Uma emanzini ukuze ashisise nakakhulu, 'ukuze iphenduke umusi. Pairs - a amanzi gaseous; ice - amanzi siqinile.
Ezinye izinto aziwa nathi zasendle kuphela umbuso owodwa. Ngokwesibonelo, siyazi emoyeni njengoba igesi, mercury - njengoba uketshezi, nensimbi - njengoba umzimba eqinile. Kodwa lezi izinto kanye zonke izinto, ngaphandle kokukhetha, ingatholakala kuzo zonke izifunda ezintathu. Ngakho, uketshezi emazingeni okushisa ngokwanele ongaphakeme eqinisa, nangaphansi okusezingeni eliphezulu - shabalala. Le gesi zingaphendulwa zibe yizindawo yokuhlanganela uketshezi, bese umzimba okuqinile. Laboratories, isibonelo, ngokuvamile kakhulu ukubhekana emoyeni uketshezi; moleno uthole emoyeni eqina. Mercury zilimaze cishe amane ngaphansi kwezingaqhwa Celsius. Iron ngamazinga ashisa kakhulu kakhulu zingaphendulwa zibe yizindawo yokuhlanganela umusi.
Impahla eyinhloko emizimbeni gaseous yikhono ukuhlakaza emkhathini; igesi ebiyelwe esitsheni banoma iyiphi isayizi, basakaza nombala phezu isitsha.
Kunalokho, uketshezi azigcina njalo ethile. Njengoba for ifomu, khona-ke alikho uketshezi - kuthatha ifomu bomkhumbi esasihumushela wawathela.
umzimba Solid akanalo nje ethile, kodwa futhi uhlobo oluthile. Kuphela ngosizo amabutho angaphandle - kokucindezelwa, ukungakhululeki, ukushaqeka - moleno ukushintsha ukuma kwezinto eziqinile. Nokho, naphezu umehluko omkhulu sangaphandle ezintathu uthi, ukwakheka atomic yamangqamuzana we indaba siyagcinwa zonke izimo ezintathu. Ushintsho kuphela Uyinhloboni isikhundla isihlobo kanye motion izinhlayiya.
Ososayensi abaningi namanje abangazange yanquma noma cha "plasma" yesine isimo ndaba. Ngakolunye uhlangothi, i-plasma chasiselwe eyaziwa kakade ezintathu uthi aggregate bengayi, ngoba le izakhiwo ayisisekelo. Nokho, it is hhayi kungase kutholakale ukuthi ngokuphelele zonke izinto kungaba kulesi "plasma" isimo.
