ʻO ka nuʻa ʻo ia ke kēkelē o ka hoʻopili ʻana o nā mea like ʻole, ʻoiai kēia parameter ana i ka nui o ka nu i kēlā me kēia nui o ka nui.
Inā loaʻa i hoʻokahi pūʻolo nā pellets Styrofoam, no ka laʻana, a me ka ʻāpana ʻelua, o ka nui like, loaʻa nā tile pālolo, maopopo leʻa e kaupaona ka lua ma mua o ka mua. ʻO Density kahi waiwai e hiki ai ke ʻike ʻia nā mea like ʻole.
ʻO kahi laʻana, ʻo ia kēpau he kiʻekiʻena 11,3 g / cm3, ka o ka waiū ʻo 1.03 g / cm3 aʻo ke kalapona monoxide, kahi kinoea ʻawahia loa no nā kānaka, ʻo 0,00125 g / cm wale nō3. ʻO ka ʻoi aku ka nui o nā kino paʻa ma mua o nā wai aʻo kēia mau mea iʻoi aku ka kiʻekiʻe ma mua o ʻenekini.
Hiki i nā moena kāpili hua, i hana ʻia me kahi mea i kapa ʻia he polyurethane a i ʻole polyester, hiki ke loaʻa ka laulā ʻokoʻa a hoʻoholo kēia, ma kahi ʻāpana, i ko lākou maikaʻi a me ka paʻa. I kēia hihia, hōʻike ʻia ka mānoanoa o ka hua i nā kilokika i kēlā me kēia mika mika (kg / m3).
ʻO ka palena iki i koi ʻia no ka hana ʻana moena moena ʻo 22 kg / m³ ia, ʻoi aku ka kaumaha o nā moena momona akā ua manaʻo ʻia ʻoi aku ka maikaʻi e hōʻalo i nā pilikia o ka ʻehaʻeha o ke kua a me ka deformation spinal; ʻoi aku ka lōʻihi o ka lōʻihi.
ʻO ka porous a me nā mea liʻiliʻi liʻiliʻi pono mau lākou ma ke ʻano ka mahana a me nā insulator kani. E lana pinepine kēia mau mea i ka wai, e like me ka cork a i ʻole ka plastic.
ʻO ke ʻano figurative o "dense"
Ma ka hoʻolōʻihi ʻia ʻana o kēia manaʻo o ka nui o ke kino ka mea i ʻōlelo ʻia kekahi mea paʻakikī, figurative, i ka wā koi i ka nui o ka nānā a i ʻole ka noʻonoʻo e hoʻomaopopo, no ka paʻakikī a pilikia paha ia.
ʻO kahi laʻana, hoʻokaʻawale ʻia kahi kumuhana ma ke ʻano he "dense" ke hakakā ia; hiki ke kapa ʻia kahi puke a i ʻole ke kiʻi ʻoniʻoni "dense" a i ʻole "dense" i kēia ʻano. ʻOiai ke kumuhana o ke koleke e koi ana i ka nui o ka hoʻopaʻa a i ʻole ka ikaika o ka abstraction a i ʻole ka hoʻopaʻanaʻau hiki ke hoʻokaʻawale ʻia e nā haumāna ma ke ʻano he "dense."
Ka nuʻu lehulehu
Ma ka ʻaoʻao ʻē aʻe, ka nui o ka heluna kanaka a manaʻo kanaka helu kēlā no ka helu o nā kānaka pākahi noʻili, inā he kanaka kēia a holoholona paha a mea kanu paha.
Nā laʻana o ka mānoanoa
Nā laʻana o nā kiʻionaʻokoʻa o nā mea kemika a i ʻole nā mea paʻakikī, a me ka lehulehu o nā kūlanakauhale:
- Ka nui o Naphtha: 0.70 g / cm3
- Ka nui o ka hau (ma 0 ° C): 0.92 g / cm3
- Ka nui o ka Mercury: 13.6 g / cm3

- Ka heluna kanaka o Mexico City (makahiki 2010): 5862 poʻe / km²
- Paraná lāʻau paina (maloo): 500 kg / m3
- Ka nui o ka ʻūhini ʻūhini ʻeleʻele (maloʻo): 800 kg / m3
- Ka nui o ka helium (ke kinoea e hoʻonui ʻia ai nā pāluna lele): 0.000178 g / cm3
- Ka nui o ka uranium: 18.7 g / cm3
- Ka mānoanoa o ka hoʻohou hou ʻana i nā lāʻau lenga i ka nahele Andean-Patagonian: 20,000 a 40,000 mau laʻana / ha.
