A amo i te whakamātautau i roto i te akoranga ahupūngao haamata ki inenga ā Defining pērā i te roa, rohe, rōrahi. whakau ana tenei he hononga i waenganui i te pāngarau (waitara nui hoki te tamaiti), me te matauranga tinana. Karanga ki te wheako o te tamaiti, whakaaro o te roa-mohiotia ki a ia nga meka i te wāhi pūtaiao o te tirohanga whai wāhi ki te hanganga o te mātau e hiahiatia ana. Ko te whakaaro o te whakangungu i roto i tenei take - te hiahia mō te whaiaro mahino-o te hou.

Ako o kiato

I roto i runga ki te tikanga o te whakangungu raruraru i te timatanga o te haapiiraa, ka taea e koe te whakapūtā he kai mohiotia: "He aha te mea taimaha: he kiro o fluff ranei te kiro o rino" O te akoranga, ngāwari e taea-tau 11-12-pakeke whakahoki te pātai rongonui ratou. Ko te tono ki te ngakau o te mea, te whai wāhi ki te kitea e arata'i tona taa ki te ariā o te kiato.

Ko te kiato o te mea - wae papatipu o tona rōrahi. matū kiato Ripanga te nuinga hakari i roto i ngā pukapuka, me ngā pukapuka tohutoro, ka taea ki te aromātai i te rerekētanga i waenganui i nga rauemi, ano te āhua hiato o te mea. Kia mahara te rerekētanga i roto i te āhuatanga ōkiko o totoka, wai me hau, kōrero i mua, whakamārama o tenei rerekētanga ko kore anake te hanganga me te whakaritenga tahi o nga matūriki, engari i roto i te āhuatanga faaiteraa pāngarau o te taonga me ki ako o te ahupūngao ki te taumata rerekē.

Whakakotahi i te matauranga o te tikanga tinana o te ariā i raro i ako taea rauemi tepu-kiato. Tamaiti, hoatu he kupu whakahoki ki te pātai: "? He aha te mea te uara o te kiato o te taonga motuhake", matau e ko te papatipu o te 1 cm ³ (ranei 1 m ³⁾ tenei matū.

Ka taea te whakaarahia te take o ngā wae kiato i tenei wā. He mea tika ki te whakaaro huarahi ki te whakawhiti wae ki ngā pūnaha tohutoro. hanga taea reira ki te pehea e whakaaro pateko tenei, tangohia atu pūnaha o tātaitanga, me te tahi atu take.

kiato

O te akoranga, e kore e taea e te ako o te ahupūngao kia oti, kahore whakaoti i te raruraru. I tenei wā he tātai tātaitanga tāuru. kiato tātai i roto i te ahupūngao kōeke 7, pea, te hononga nui tinana tuatahi mō te tamariki. utu ia tokanga makehe rite ki te hua o ako te kiato o ngā ariā e kore anake, engari ano hoki ki te tikanga whakangungu o whakaoti rapanga.

Ko reira i tenei wā o te hātepe whakatakotoria te rongoā tinana mahi rorohiko tono Māoritanga o te tātai taketake, whakamāramatanga tauira. A haapii i te tātaritanga o te raruraru, he tikanga mo te rapu o unknown, rawa te whakamahi o ngā waeine ariki ngana ki te whakamahi i te pā ana pērā i te mātotoru tātai i roto i te ahupūngao.

He tauira o te whakaoti rapanga

TAUIRA 1

Whakatau i te taonga kupiki hangaia taimaha 540 karamu, me te rōrahi o te 0.2 DM ^3.

ρ -? m = 540 g, V = 0,2 DM ³ = 200 cm ³

tātari o

I runga i te pūtake o te pātai o te raruraru, i matau ai tatou e te tautuhi i te rauemi i ai hanga te kupiki, e tatou totoka tepu densities.

Na reira, tautuhi tatou te kiato o te taonga. I roto i te tepu, i homai tenei uara i roto i g / cm ^3, na te rōrahi o te DM whakawhiti ³ cm ^3.

whakatau

Na roto i te definition: ρ = m: V.

Ko matou: rōrahi, taimaha. Ka taea te tātai taonga kiato:

ρ = 540 g: 200 cm ³ = 2.7 g / cm ^3, e hāngai ana ki te konumohe.

Whakahoki kupu: i hanga te kupiki te o te konumohe.

Whakatau i o ētahi atu taurangi

Mā te whakamahi i te tātai kiato tātaitanga taea ki a koe te tautuhi me te tahi atu inenga ā-. Mass, rōrahi, āhuatanga rārangi o nga tinana e pā ana ki te rōrahi tatau ngāwari i roto i ngā raruraru. Knowledge o tātai pāngarau whakatau te rohe, me te rōrahi o ngā tau āhuahanga whakamahia i roto i tono e taea ki te whakamārama i te hiahia mo te ako o pāngarau.

TAUIRA 2

Te whakatau i te matotoru o te apa parahi, pani nei te ki te wāhi mata tūemi o 500 cm ^2, ki te mea i mohiotia he e pau paninga 5 go o parahi.

h -? S = 500 cm ^2, m = 5 g, ρ = 8,92 g / cm ^3.

tātari o

matū kiato Ripanga ki te whakatau i te nui o parahi kiato.

whakamahi tatou i te tātai mō te tātai i te kiato. I roto i tenei tātai ko te rōrahi o te taonga, e hāngai ana i runga i nei e taea e tetahi te whakatau i te āhuatanga rārangi.

whakatau

Na roto i te definition: ρ = m: V, engari i roto i tenei tātai i te uara e hiahiatia ana, na whakamahi tatou:

V = S x h.

Whakakapi i roto i te tātai taketake, whiwhi tatou: = ρ m: Sh, te wahi:

h = m: S x ρ.

whakatatau matou: h = 5 g ⁽² x 500 cm 8,92 g / cm ³⁾ = 0.0011 cm = 11 um.

A: Ko te matotoru o te apa parahi he 11 microns.

faaotiraa whakamātau o te kiato

faaite te āhua whakamātautau o te pūtaiao tinana i roto i ngā taiwhanga. I tenei wā te pūkenga riro o te whakamātau, he whakamārama o ona kitenga.

Ko te mahi mahi o te whakatau i te kiato o te mea ngā:

• Whakatau i te kiato o te wai. I tenei wā, ko eé, whakamahia kua mua rango, ngāwari whakatau te kiato o te wai mā te whakamahi i te tātai.
• Whakatau i o te rauemi kiato tika hanga te totoka. Ko tenei mahi hoki e kore i roto i te feaa, rite kua kōrero he mahi tātai rite me te wheako riro mā te ine i te rōrahi o ngā āhuatanga rārangi o te tinana.
• Whakatau i o te mātotoru kōhikohikotia āhua totoka. I roto i te whakahaere i tenei mahi whakamahi tatou te tikanga o te whakatau i te rōrahi o te tinana kōhikohikotia āhua i te tikanga o te ipurau. He mea pai ki te fakaongo atu i te āhuatanga o tenei tikanga: kaha Mārō ki teke'i inu, te rōrahi o e ko te rōrahi tinana. tukua mahi Next te paerewa.

Tūmahi o whīwhiwhi tiketike

Ka taea e haafifi i te mahi mā te whakahere tamariki whakatau i te taonga i hanga i nei te tinana. Whakamahia i roto i tenei Matū tepu kiato taea ki te utu whakarongo ki te hiahia mo te kaha ki te mahi ki ngā mōhiohio whakamārama.

I roto i te whakaoti rapanga whakamātautau, e hiahiatia ana ngā ākonga ki te whai i te matauranga e tika ana i roto i te whakamahi o ngā pūrere tinana me ngā waeine whakawhiti. E mea pinepine, Ko te mea ai te maha nui o ngā hapa me mea kohakore i tenei. Pea ki tenei wā te ako o te ahupūngao ko te whakarato wā ake, ka taea e te reira ia tatou ki te whakarite i te mōhiotanga me te wheako o te ako.

kiato nuinga

He ako o te taonga parakore, o te akoranga, ngā, engari pehea maha e tupu matū ma? I roto i te ora ia rā whakatau tatou ki ngā ranunga me alloys. Me pēhea te ki te kia i roto i tenei take? E kore e te ariā o te kiato nuinga tukua ākonga ki te hanga hape angamaheni, me te whakamahi i te uara toharite o te kiato o te mea.

Whakamārama i te mea he mea nui ki te hoatu i te whai wāhi ki te kite me te ite i te rerekētanga i waenganui i te kiato o te mea, me te mātotoru nuinga tu i roto i te tīmatanga o te wāhanga. Mahara ki tenei wehewehe he tika ki te ako atu o te ahupūngao.

Tino ngā Ko te rerekētanga i roto i te take o ngā rauemi nuinga. Tukua te tamaiti ki te ako kiato nuinga i runga i te rauemi hiri rānei, te rahi o te matūriki takitahi (kirikiri, onepu me te rite. D.) I taea i roto i te rangahau tuatahi.

Ko te kiato whanaunga o te matū

Whakatauritenga o ngā āhuatanga o ngā matū rerekē feunga ngā i runga i te pūtake o ngā uara whanaunga. Whanaunga kiato o te mea - tetahi o enei uara.

Ka rite ki te ōwehenga o te kiato o te taonga ki te kiato tohutoro, takoto tenei uara kei te whakamahi i te pycnometer. Otiia i roto i te akoranga kura o pūtaiao māori, e kore e whakamahia tenei kōrero, ko reira ngā ki te ako hohonu o te (maha kōwhiri).

taumata Olympiad o ako o ahupūngao me te matū e taea pā te ariā o "kiato whanaunga o te rauemi ki te whakapai kanohi ki te hauwai." Ko te tikanga kua tono te reira ki hau. Hei whakatau i te kiato whanaunga o te hau ko te ōwehenga o te papatipu titiwha o te hau whakamātautau ki te papatipu titiwha o hauwai. Ko te whakamahi o te papatipu rāpoi- kore te araia.
