Izinhlobo Zamandla Amandla umqondo oyisisekelo ku-physics obhekisela ekhonweni lokwenza umsebenzi. Amandla akhona ngezindlela eziningi, futhi ukuqonda lezi zinhlobo kubalulekile ekuqondeni ukuthi indawo yonke isebenza kanjani. Lesi sihloko sizoxoxa ngezinye zezinhlobo eziyinhloko zamandla, ukuthi zisebenza kanjani, kanye nezibonelo zezicelo zazo ekuphileni kwansuku zonke. Amandla e-Kinetic … Funda kabanzi
Isingeniso: Amandla avuselelekayo amandla akhiqizwa emithonjeni yemvelo engavuselelwa ngokwemvelo ngesikhathi esifushane. Le mithombo yamandla ibalulekile emizamweni yokunciphisa ukuthembela kumafutha angaphansi komhlaba kanye nokunciphisa imiphumela emibi emvelweni. Lesi sihloko sizoxoxa ngezinhlobo ezahlukene zamandla avuselelekayo, izinzuzo zawo, izinselele abhekene nazo, kanye nezibonelo zezicelo zawo… Funda kabanzi
Ama-nanomaterial ayizinto ezinobukhulu obuncane kakhulu, ngokuvamile esikalini se-nanometer (1 nm = 10-9 amamitha). Kulesi sikali, izakhiwo zezinto zingahluka kakhulu uma kuqhathaniswa nalezo ezisesikalini esikhulu. Ukuqonda isakhiwo se-athomu kubalulekile ekufundweni kwama-nanomaterial ngoba ukuziphatha, izakhiwo, kanye nokusetshenziswa kwama-nanomaterial kuncike kakhulu ekusebenzisaneni phakathi...

I-Atomic Radius njenge-Periodic Property ye-Elements I-atomic radius ingenye yezakhiwo ze-periodic zezinto ezishintsha njalo kuthebula le-periodic. Ukuqonda ukuhlukahluka kwe-atomic radius kubalulekile ekubikezeleni izakhiwo zomzimba nezamakhemikhali zezinto kanye nokuziphatha kwazo kuma-compounds. Lesi sihloko sizoxoxa ngomqondo we-atomic radius, ukuthi ishintsha kanjani kuthebula le-periodic, nokuthi kungani… Funda kabanzi
Ukucushwa kwe-electron kuwumqondo obalulekile kumakhemikhali ochaza ukusatshalaliswa kwama-electron ngaphakathi kwe-athomu noma i-molecule. Ukuqonda ukucushwa kwe-electron kuvumela ososayensi ukubikezela izakhiwo zamakhemikhali nezomzimba zento noma i-compound. Lesi sihloko sizoxoxa ngezimiso eziyisisekelo zokucushwa kwe-electron, ukuthi ama-electron ahlelwe kanjani kuma-orbital, kanye nokubaluleka kwawo kumakhemikhali. Izimiso Eziyisisekelo Zokucushwa Kwe-Electron… Funda kabanzi
Ama-athomu ayizinyunithi eziyisisekelo zezinto ezakha konke endaweni yonke. Ukuqonda isakhiwo se-athomu kubalulekile ekuqondeni izenzakalo ezihlukahlukene zomzimba nezamakhemikhali eziyisisekelo sempilo nobuchwepheshe besimanje. Lesi sihloko sizoxoxa ngesakhiwo se-athomu, umlando wokutholakala kwayo, izingxenye zayo eziyinhloko, nokuthi ukuqonda kwethu ama-athomu kuye kwashintsha kanjani ngokuhamba kwesikhathi. Umlando Wokutholwa… Funda kabanzi
I-nanotechnology igatsha lesayensi elithuthuka ngokushesha elithembisa ukuguqula imikhakha efana nemithi, ubuchwepheshe bolwazi, amandla, kanye nemvelo. Igama elithi "nanotechnology" libhekisela ekuphathweni kwezinto esikalini se-nanometer, ingxenye eyodwa kweziyizigidigidi zemitha, okuvumela ososayensi ukuthi bakhe futhi balawule izakhiwo ngokunemba okumangalisayo. Lesi sihloko sizochaza… Funda kabanzi
I-Chemistry iwukufunda izakhiwo, ukwakheka, kanye nezinguquko zezinto. Njengoba isayensi ithuthuka, ososayensi bakhe imithetho eminingana eyisisekelo esekela yonke imibono yamakhemikhali kanye nokusetshenziswa kwawo. Le mithetho ayibalulekile nje kuphela ekuqondeni okuyisisekelo kwe-chemistry kodwa futhi iwusizo kakhulu ekusetshenzisweni okuhlukahlukene okusebenzayo kwezobuchwepheshe, kwezemithi, kanye nemvelo. Lesi sihloko sizo… Funda kabanzi
Ukusabela kwamakhemikhali inqubo lapho into eyodwa noma eziningi ziguqulwa zibe yinto eyodwa noma eziningi ezintsha ezinezakhiwo ezahlukene. Le nqubo ibalulekile kumakhemikhali nakwezinye isayensi ngoba iyisisekelo sezinto eziningi zemvelo kanye nobuchwepheshe. Lesi sihloko sizoxoxa ngezici zokusabela kwamakhemikhali, izinhlobo ezahlukene zokusabela kwamakhemikhali, nokuthi ungakubhala kanjani kahle... Funda kabanzi
Isingeniso I-green chemistry, noma i-estabilite chemistry, insimu egxile ekwakhiweni kwemikhiqizo yamakhemikhali kanye nezinqubo ezinciphisa noma eziqeda ukusetshenziswa kanye nokukhiqizwa kwezinto eziyingozi. Izimiso ze-green chemistry zihlose ukuvikela imvelo kanye nempilo yabantu ngokunciphisa imiphumela emibi yemisebenzi yamakhemikhali. Lesi sihloko sizoxoxa ngemisebenzi ehlukahlukene esekela izimiso ze-green chemistry, okuhlanganisa nokusungula izinto ezintsha... Funda kabanzi
