Kuwerengetsa malita angati a madzi 1 kyubu

Kodi madzi, aliyense amadziwa. Ichi ndi madzimadzi yemweyo amene amatuluka kuchokera mpopi wathu timamwa, ife kusamba ndi ntchito kuphikira. Iye atadzazidwa nyanja, nyanja ndi nyanja, izo uli m'nthaka, mobisa ndi kumwamba. Anathira pansi monga mvula pa nyengo yofunda, ndi yozizira chimakwirira dziko lonse mu mawonekedwe a chisanu ndi ayezi. Inde, ndi munthu pafupifupi makumi asanu ndi atatu peresenti wapangidwa madzi omwewo. Ngakhale anasiya kusukulu mukudziwa kuti mankhwala opangidwa ndi madzi kuwerenga monga H ₂ O ( «awiri Al"), ndiponso mukudziwa kuti H - ndi wa hydrogen, ndi pansi O akatswiri kumvetsa oxygen.

Popanda madzi padziko lathuli pakhale palibe zamoyo. Zachilengedwe amaopa ife chifukwa ambiri a madzi pa dziko Si bwino kumwa chifukwa lili wambirimbiri mchere - nyanja ndi madzi nyanja. Ndipo m'matangadza madzi zaposachedwa za makilomita kiyubiki 80,000. Ndi kwambiri kapena pang'ono? Tiyeni tiwone yaitali bwanji adzakhululukidwa amayezedwa kiyubiki mamita ndi malita, ndiko kuti, tikupeza angati malita a madzi 1 kyubu, chifukwa mosamalitsa chilankhulire, kilometre kiyubiki - uwu si zokhudza zonse chimodzi. Mmodzi kilometre kiyubiki lili biliyoni ndi kiyubiki mamita.

manambala ndi chidwi, sichoncho? Madzi padziko lathuli zambiri. Koma ndi angati a bwino kuti ife malita? Ndipotu, sitinayambe musati kuyeza madzi kiyubiki mamita, ife kuyeza buku la malita zakumwa. Choncho, tiyeni kumvetsa malita angati madzi kyubu wina. Kuvina kuyambira dzina. mita imodzi kiyubiki ndi kyubu ndi mbali wofanana mita imodzi. Tiyeni tsopano kukonzekera kumanga kyubu. Ngati ife mu kyubu izi kutsanulira lita imodzi ya madzi, mwachitsanzo, ndi zitini wamba lita kapena chingwe chikho, izo kuphimba yekha pansi kyubu lapansi. Ndi yankho ku funso lakuti: "? Malita angati 1 kyubu" - tingathe kupeza pokhapokha ngati inu lembani izo ndi kyubu pamwamba.

Zikuonekeratu kuti akuthamanga lita mtsuko wa mpopi kyubu palibe akufuna. Chotero, inu mukhoza kugwiritsa ntchito ndowa kapena kungoti kumanga kyubu ang'onoang'ono. Ndimaganiza ife tonse tikudziwa ndi timadziwa kuti njira yosavuta kugawanitsa ndi 10. Choncho tiyeni kukonzekera kumanga kyubu ndi mbali decimeter. mtsuko wathu wodzazidwa kyubu ili pamwamba! Hooray!

Tsopano n'zotheka pulayimale kuwerengetsa mmene malita a madzi kyubu wina ambiri. Ngati lita imodzi ndi wofanana decimeter kiyubiki chimodzi, inu muyenera kuwerenga angati a decimeters izi kiyubiki pa mita kiyubiki. Ngati timatenga lalikulu, n'zotheka kudziwa mwamsanga - iwo ndendende 100, ndiyo 10 digiri yachiwiri. Koma ife tiribe apakati ndi kyubu. Choncho, kodi malita ambiri a madzi 1 kyubu? Ndiko kulondola ndendende 1,000.

Muli kupirira zokwanira kuthamanga nthawi 1,000 ndi lita mtsuko? Ndikukayika izo. masamu A, kapena m'malo ngakhale masamu, kutheka ndawala monga madzi. Tsopano ife tikudziwa chimodzimodzi angati malita a madzi 1 kyubu. Tikhonza kutembenuza kiyubiki mamita kuti makilomita kiyubiki, ndipo n'zotheka kudziwa zimene kotunga madzi pa dziko.

Ndipotu ina chidwi ndi lita imodzi ya oyera madzi (otchezedwa) m'mikhalidwe yachibadwa akulemera ndendende kilogalamu imodzi. kotero tsopano, podziwa malita angati a madzi 1 kyubu, tikhoza kuwerenga, ndi kulemera onse a madzi pa dziko. Ndipo ngati mukufuna kudziwa kulemera okwana madzi mu nyanja onse ndi nyanja, ndiye iwe uyenera kukumbukira kuti mchere madzi kachulukidwe ndi apamwamba kuposa mwatsopano, choncho kulemera lita imodzi ya madzi mchere ayenera kukhala.
