Ubuningi

-Delile

• Umqondo ongokomfanekiso we "dense"
• Inani labantu
• Izibonelo zobuningi

I- ukuminyana yizinga lokuxinana kwezinto ezihlukile, kusukela kule pharamitha ilinganisa inani lobukhulu obukhona ngevolumu yeyunithi.

Uma iphakethe elilodwa liqukethe amaphilisi e-Styrofoam, ngokwesibonelo, nephakeji lesibili, elilinganayo, liqukethe amathayili e-ceramic, kuyacaca ukuthi leli lesibili lizobe likala kakhulu kunelokuqala. Ubuningi buyisici esivumela izinto ezihlukile ukuthi zikhonjwe.

Isibonelo, yena hola inesisindo esingu-11.3 g / cm³, the ubisi ingu-1.03 g / cm³ naleyo ye-carbon monoxide, igesi enobuthi kakhulu kubantu, ingu-0,00125 g / cm nje³. I- imizimba eqinile ijwayele ukuba nobukhulu obukhulu kunoketshezi futhi lezi nazo zinobuningi obuphakeme kune- amagesi.

Omatilasi benjoloba, abenziwe ngento ebizwa nge-polyurethane noma i-polyester, bangaba nobuningi obuhlukile futhi lokhu kunquma, ngokwengxenye, ikhwalithi nokuqina kwabo. Kulesi simo, ubukhulu begwebu bukhonjiswa ngamakhilogremu ngemitha ngalinye elilodwa (kg / m³).

Ubuncane bokunconywa kokwenza omatilasi ingu-22 kg / m³, omatilasi abajiyile baba nzima kepha babhekwa njengabangcono ukugwema izinkinga zobuhlungu obuphansi emuva nokukhubazeka komgogodla; futhi zihlala ziqinile.

I- izinto ezibandayo neziminyene imvamisa ziwusizo njenge amazinga okushisa kanye nemisindo evimbela ukushisa. Lezi zinto zivame ukuntanta emanzini, njengokhokho noma ipulasitiki.

Umqondo ongokomfanekiso we "dense"

Ngokwandiswa kwalo mqondo wokuqina komzimba ukuthi okuthile kuthiwe kuminyene, ngokomfanekiso, lapho kudinga ukunakwa okuningi noma ukugxila ukuze kuqondwe, kungaba ngenxa yokuthi inzima noma inzima kangakanani.

Isibonelo, isihloko sihlukaniswa ngokuthi “sinyene” uma siphikisana; incwadi noma i-movie ingabizwa ngokuthi "i-dense" noma "dense" nakulo mqondo. Ngisho nesifundo sasekolishi esidinga ukutadisha okuningi noma umzamo wokukhipha noma wokukhumbula ngekhanda singahlukaniswa ngabafundi ngokuthi "sinyene."

Inani labantu

Ngakolunye uhlangothi, ukuminyana kwabantu yi- umqondo wabantu okubangela i- inani labantu ngeyunithi ngayinyeubuso, noma ngabe ngabantu noma izilwane noma izitshalo.

Izibonelo zobuningi

Izibonelo zobukhulu obuhlukile be- izakhi zamakhemikhali noma izinto eziyinkimbinkimbi, kanye nobuningi babantu emadolobheni:

1. Ubuningi beNaphtha: 0.70 g / cm³
2. Ubuningi beqhwa (ku-0 ° C): 0.92 g / cm³
3. Ubuningi beMercury: 13.6 g / cm³
4. Ubuningi bukamatilasi wegwebu ojwayelekile: 28 kg / m³
5. Inani labantu eMexico City (unyaka ka-2010): izakhamuzi ezingama-5862 / km²
6. Ubuningi beParaná pine wood (omile): 500 kg / m³
7. Ubuningi bezinkumbi ezimnyama (ezomile): 800 kg / m³
8. Ubuningi be-helium (igesi okugcwala ngayo amabhaluni): 0.000178 g / cm³
9. Ubuningi be-uranium: 18.7 g / cm³
10. Ubuningi bokuvuselela izihlahla ze-lenga ehlathini lase-Andean-Patagonian: ama-20 000 kuya ku-40,000 ama-specimens / ha.
