Isihloko mayelana nencazelo yokushisa kanye nokulingana kokushisa
Incazelo yokushisa
Wake wathinta iqhwa? Uzizwa kanjani uma izandla zakho zithinta iqhwa? Kuthiwani uma lokho okuthintayo kungumlilo? Uma uthinta iqhwa, izandla zakho zizwa zibanda, uma uthinta umlilo, izandla zakho zizwa zishisa. Kusho ukuthini ukushisa, ukufudumala, ukubanda, nokubandayo?
Umqondo wokushisa uqala ekushiseni nasekubandani okubonwa umuzwa wethu wokuthinta. Ngokusekelwe kulokho okuzwakala umuzwa wokuthinta, sithi into ishisa kakhulu kunenye into noma into ipholile kunenye. Izinto ezishisayo zinamazinga okushisa aphezulu, kuyilapho izinto ezibandayo zinamazinga okushisa aphansi. Uma into ipholile, izinga lokushisa liphansi. Ngokuphambene nalokho, uma into ishisa kakhulu, izinga lokushisa liphakeme. Isilinganiso sokushisa noma ukubanda kwento sibizwa ngokuthi izinga lokushisa. Esihlokweni se-gas kinetic theory, uzoqonda ngokujulile incazelo yokushisa; kwenzekani kuma-molecule avela entweni ukuze izwakale ishisa, ifudumele, ipholile noma ibanda.
Ubukhulu bokushisa noma ukubanda yinto esekelwe ekuthinteni kuphela, noma umuzwa womuntu wokuthinta awubonakali. Wonke umuntu angakuzwa ukushisa noma ukubanda kwento emazingeni ahlukene. Ingane ingazizwa ubuhlungu lapho ithinta amanzi angashisi kakhulu kubantu abadala. Ngokufanayo, naphezu kokuthinta into efanayo, ukushisa okuzwiwa izingxenye ezahlukene zomzimba kungase kungafani. Ngakho-ke, sidinga idivayisi engasetshenziswa ukukala izinga lokushisa ngokuqiniseka futhi engathenjwa yiwo wonke umuntu.
Ukulingana kokushisa
Uma izinto ezishisa kakhulu zithintana nezinto ezishisa kakhulu, okunye ukushisa okuvela ezintweni ezishisa kakhulu kuya entweni eshisa kakhulu kuze kube yilapho zombili izinto zinezinga lokushisa elifanayo. Uma amanzi ashisayo ethintana neqhwa, okunye ukushisa okuvela emanzini ashisayo kuya eqhweni. Ukudluliselwa kokushisa kuyama uma ingxube yokushisa neqhwa ifinyelela izinga lokushisa elifanayo. Uma inhlanganisela yamanzi ashisayo neqhwa ifinyelela izinga lokushisa elifanayo, ingxube yamanzi ashisayo neqhwa isesimweni sokulinganisela ukushisa. Ngokufanayo, lapho amanzi abilayo ethintana namanzi abandayo, okunye ukushisa kusuka emanzini ashisayo kuya emanzini abandayo.
Ukudluliselwa kokushisa kuyayeka ngemva kwengxube yamanzi ashisayo, bese amanzi abandayo ephenduka amanzi afudumele. Lapho wonke amanzi eshisa kakhulu, wonke amanzi asuke esefinyelele izinga lokushisa elifanayo. Lapho ingxube yamanzi ashisayo nabandayo ifinyelela izinga lokushisa elifanayo, ingxube yamanzi ashisayo nabandayo iba sebulinganisweni bokushisa.
Uma izinto ezimbili noma ezingaphezu kwezimbili ezinamazinga okushisa ahlukene zithintana zize zifinyelele izinga lokushisa elifanayo, izinto ezifinyelele izinga lokushisa elifanayo kuthiwa zisesilinganisweni sokushisa.
