Wake wazibuza ukuthi kungani amafu ehlala phezulu futhi ehla ezintabeni noma emagqumeni ngesikhathi semvula? Lapho kufika isikhathi semvula, amafu angehla ngisho nasezintabeni noma emagqumeni bese ebuyela phezulu. Kungani amafu ehla, futhi yini ebangela ukuba akhuphukele phezulu futhi?
Ubuningi
Ukuze uqonde lokhu, qala uqonde umqondo ukuminyanaUbuningi buyisilinganiso sobuningi nobuningi, esivezwa ngokwezibalo ngesibalo ρ = m / V, lapho u-ρ ewuphawu lobuningi, u-m uwuphawu lobuningi kanti u-V uwuphawu lobuningi. Isibonelo, uma ubunzima = 1 kg kanye nobuningi = 1 m3 bese kuthi ubuningi = 1/1 = 1 kg/m3Uma isisindo = 1 kg kanye nomthamo = 2 m3 bese kuthi ubuningi = 1/2 = 0,5 kg/m3Ngokufanayo, uma isisindo = 1 kg kanye nomthamo = 4 m3 bese kuthi ubuningi = 1/4 = 0,25 kg/m3Kungaphethwa ngokuthi uma ivolumu ikhuphuka kuyilapho isisindo sihlala singaguquguquki, ubuningi buyancipha.
Ngakolunye uhlangothi, uma isisindo = 4 kg kanye nomthamo = 1 m3 bese kuthi ubuningi = 4/1 = 4 kg/m3Uma isisindo = 2 kg kanye nomthamo = 1 m3 bese kuthi ubuningi = 2/1 = 2 kg/m3Ngokufanayo, uma isisindo = 1 kg kanye nomthamo = 1 m3 bese kuthi ubuningi = 1/1 = 1 kg/m3Kungaphethwa ngokuthi uma ivolumu ihlala ingaguquki kuyilapho isisindo sincipha, ubuningi buzoncipha.
Ukwanda kanye nengcindezi
Wake wayibona intuthu evela emlilweni? Uma kungekho moya, intuthu ivame ukukhuphukela phezulu. Intuthu inokushisa okuphezulu (ukushisa), okubangela ukuthi ikhule. Lokhu kukhula kwandisa umthamo wentuthu, kunciphisa ubuningi bayo.
Ubuningi bentuthu bungaphansi kobuningi bomoya ozungezile, ngakho-ke intuthu isunduzelwa phezulu ngumoya ozungezile. Lokhu kusunduzwa kwenzeka ngenxa yokwehluka kwengcindezi. Intuthu iya phezulu ize ime endaweni lapho ubuningi bomoya bulingana nobukhulu bentuthu. Ubuningi buyalingana, ngakho-ke akukho mehluko wengcindezi.
Amandla Adonsela Phansi
Okuphakeme kakhulu ebusweni bomhlaba, amandla adonsela phansi Amandla asebenza kuleyo ndawo ayancipha. Ngakho-ke, lapho usondela ebusweni boMhlaba, kulapho umoya uba mkhulu khona, kuyilapho lapho uphakeme ngaphezu kobuso boMhlaba, kuba nomoya omncane. Kuyo leyo volumu efanayo, isisindo somoya ekuphakameni singaphansi kwesisindo somoya eduze kobuso boMhlaba. Ivolumu ihlala ingaguquguquki kuyilapho isisindo sincipha, ngakho-ke ubuningi bomoya buyancipha. Ngakho-ke, lapho uphakeme ngaphezu kobuso boMhlaba, ubuningi bomoya buncipha.
Amafu aphakeme kakhulu lapho ubuningi bawo bufana nobukhulu bomoya ozungezile.
Ngesikhathi semvula, amafu angehlela emithambekeni yezintaba noma emagqumeni ngoba ubuningi bawo bukhulu kunomoya ozungezile. Lokhu kwanda kobuningi bamafu kungabangelwa ukwanda kobuningi bamafu ngenxa yokuba khona komhwamuko wamanzi noma ukwehla komthamo ngenxa yokwehla kokushisa kwamafu. Ukwehla kwamafu emoyeni kufana nokuwa kwetshe emanzini, njengoba ubuningi betshe bukhulu kunobamanzi.
Uma useduze nomthambeka wentaba noma igquma, ubuningi befu bufana nobuningi bomoya ozungezile. Amafu aya phezulu futhi uma ubuningi bawo buphansi kunobuningi bomoya ozungezile. Izinguquko kubuningi befu noma bomoya zenzeka ngenxa yezinguquko kubukhulu noma ivolumu. Ubuningi buyashintsha lapho izinga lokushisa lishintsha, njengoba kuxoxwe ngakho esihlokweni sokwanda. Ubuningi buyashintsha lapho okuqukethwe umhwamuko wamanzi kushintsha.
Uma ufuna ukuqonda okwengeziwe, sicela ufunde lo mqondo ukuntanta i-serta ukuntanta nokucwila. Ukuntanta, ukukhuphuka kanye nokucwila kungenzeka oketshezini olufana namanzi nomoya.
