Izakhiwo nomfutho wegesi

Ukucindezela kuyinkomba ebonisa ukulinganisa kwamandla abhekene nendawo ebhekene nayo, endaweni yendawo.

Impahla ehlukile yegesi yikhono layo lokugcwalisa isitsha noma isitsha ngaphakathi kwesikhala esivinjelwe. Okusho ukuthi, isitsha sigcwele igesi ngokulinganayo. Njengoba igesi igcwele, igesi igxuma ngokumelene nezindonga zamanzi. Uma singangeni ekuhlaziyweni kwesakhiwo segesi, singasho ukuthi ukucindezelwa kwegesi kulinganisela kulo lonke umkhumbi. Kodwa, unikezwe isakhiwo samangqamuzana gesi, umuntu akakwazi ukukhuluma ngesimo saso sokuzolile. Ama-molecule ahlala ehamba futhi ahlasele izindonga, ehamba ndawonye. Endaweni eyodwa, lezi zishaya zingaba namandla kakhulu, kanti kwezinye, zingabikho ngokuphelele. Lokhu kuhamba kwama-molecule kuyingozi.

Ebhekene nesithiyo, i-molecule isebenza ngayo ngamandla aningana nomkhiqizo we-molecule ngejubane layo. Kusukela odongeni, i-molecule iphindaphinda le nkomba. Lo mphumela kufanele wandezwe ngenani lezinyosi ngomzuzwana ngecentimitha yesigcawu. Isibonisi esiphumela ngokuya komthetho kaNewton silingana namandla asebenza kule sayithi, athulwe ngesikhathi sesenzo. Inani elifunyenwe yi-ingcindezi yenkampani yegesi.

Yiziphi izici ezithinta ukucindezelwa kwegesi?
Okubaluleke nakakhulu ukulinganisa kwamagesi. Ngamanye amazwi, lokhu kuyinamba yama-molecule esesiswini esinikeziwe. Isibonelo yinqubo yokwehlisa amathayi.

Ipharamitha yesibili ukushisa kwengxube yegesi. Ingcindezi ingashintsha ngaphansi kwethonya lezici ezimbili ngesikhathi esisodwa: ngokushintsha kokushisa noma ushintsho ngevolumu. Kodwa ngayinye yalezi zikhombisi inomthelela omubi kwimingcele yenye into. Ukucindezeleka kwegesi okungcono, okungukuthi, ukulingana kwayo, kwenzeka ngokushisa okulinganiselayo nemiphumela emihle.

Lapho ingcindezi yegesi kuzo zonke iziqukathi iba yifane, ukulinganisa okuyimishini kuhlela. Kuleli qophelo, ukunyakaza kumiswe ezingxenyeni ezihlukene zenhlanganisela yegesi. Ukulingana kwe-thermal kuphawulwe ngesikhathi lapho izinga lokushisa liba khona okwehlukile kwizigaba ezahlukene zomkhumbi futhi akukho ukushintshana kokushisa phakathi kwezinxenye zegesi.

Kuzo zonke izinto ezishiwo, kungaphetha ngokuthi ukucindezelwa kwegesi kunqunywa ukunyakaza kwama-molecule kanye nemithelela yabo emadongeni omkhumbi. Uma unciphisa inani legesi emkhunjini, ingcindezi izokhula. Ngakolunye uhlangothi, lapho inani legesi elithandeni likhuphuka, ingcindezi iyancipha. Le mithetho iphumelela kumazinga avamile okushisa nokushisa kwegesi.

Njengoba izinga lokushisa likhuphuka, ingcindezi yegesi iyanda. Lokhu kwenzeka kuphela uma ubuningi begesi bungashintshi.

Ukulinganisa kwengcindezi yegesi kwenzeka ngaphandle kokusebenzisa ifomula. Lokhu kuyadingeka ekuzivocavoca kanye nokuhlolwa okusebenzayo. Ukuze ulinganise ukucindezela komoya , kuyadingeka kuphela isibonakaliso se-atmospheric pressure. Ukuze ulinganise ukucindezelwa kwegesi kusitsha esivaliwe, kudingeka amanye amadivayisi asizayo: i-barometer, i-thermometer, ibhalansi, i-manometer.

Umoya uyinhlanganisela yegesi. Ukuze ulinganise ukucindezela komoya, ungasebenzisa i-barometer evamile-engavumelekile. Ezingxenyeni zayo zokusebenzisa izilinganiso ezifana nomkhathi noma amamitha ayi-mercury. Ungasebenzisa i-barometer ye-mercury, engcono kakhulu, kodwa enembile kakhulu.

Ukuze ulinganise ingcindezi esitsheni esivaliwe, i-manometer ivame ukusetshenziswa. Ukuze uthole izilinganiso ezinembile, i- gauge ye- electronic gauge isetshenziswa, lapho uhla lokulinganisa lungashintshwa khona.

Uma izici eziyisisekelo zegesi ziyaziwa, ke singasebenzisa ifomula yokubala ingcindezi yayo.
