Imiqondo ye- ukushisa nokushisa zihlobene kakhulu, ngoba ukushisa kungumbono wesidalwa esiphilayo sokushisa okuphezulu, kanti ukushisa kungubuningi bomzimba obukhombisa inani lokushisa.
Ukushisa yiwo wonke amandla akhiqizwa ukuhamba kwama-molecule entweni ethile, kanti izinga lokushisa liyisilinganiso samandla wamangqamuzana ajwayelekile.
Ukushisa kuya ngesivinini lapho izinhlayiya zihamba khona. Ubungako, usayizi nenombolo yezinhlayiya nakho kuyayithonya. Izinga lokushisa alincikile kulezi ziguquko.
Ukushisa kwandisa noma kunciphisa izinga lokushisa. Ukwengeza ukushisa kwandisa izinga lokushisa; lapho ususa ukushisa, kuyehla.
Ukushisa kungamandla, kanti ukushisa kuyisilinganiso sakho.
Ake siye kusibonelo:
Ukushisa kwekhofi enkomishini kungafana nokushisa kwekhofi kujeke wamalitha amahlanu; kodwa-ke, kuzoba nokushisa okwengeziwe kojeke, ngoba uma kunoketshezi oluningi, kuzoba namandla athe xaxa okushisa.
Ukushisa: Ukushisa kungena emzimbeni kunqubo eyaziwa ngokuthi Ukushisa, futhi iyunithi yokukala ebhekisa enanini lamandla ashisayo adingekayo ekudlulisweni ibizwa ama-calories, y imele inani elinamandla. Okubalulekile kunendawo yokushisa, ngoba kuhlobene nokuhamba kwezinhlayiya ezingaphakathi kuyo.
Ngemuva kwalokho, iyunithi yokukala ukushisa imele inani lamandla elidingekayo ukudlulisa lisuka kwelinye iyunithi liye kwelinye, futhi ikhalori, noma iJoules: ikhalori elilodwa limele ama-4,184 Ama-Joules.
Ithempelesha: Izinga lokushisa limelelwa ngamayunithi wokulinganisa ajwayelekile, nawo alinganisa umsebenzi wama-molecule ngaphakathi kwendaba. Izinkomba zezinga lokushisa ziveza imininingwane ehlukahlukene yendaba, njengombuso, ukuncibilika, nevolumu.
Ngokuphathelene nombuso, singakuqinisekisa ukuthi kunezinga elithile lokushisa (elihlukile ngokuya ngento), lapho selidlulile, umzimba uyeka ukuqina futhi ube uketshezi, futhi elinye izinga lokushisa elake ladlula, lisuka ekubeni uketshezi liye ekubeni yisisi .
I- amayunithi wokulinganisa ukushisa okuvamile yilezi:
- UCelsius: Cabanga ngamadigri ayi-0 ezingeni lapho amanzi asuka esiqinile aye ketshezi, ne-100 kulelo zinga asuka kulo kusuka kuketshezi kuya kugesi,
- I-Fahrenheit: Lapho izinga lokushisa liphendula inhlanganisela yezinto ezenza u-0 no-100,
- UKelvin: Iyunithi lokushisa okuphelele, u-zero Kelvin uyiphuzu lapho izinto zenza khona ukunyakaza okuncane okungenzeka.
Bhekafuthi: Izibonelo Zokuguqulwa Kwethempelesha
I- izinga lokushisa Kuyinto ebaluleke kakhulu emzimbeni, ngoba indlela ebalulekile ye-homeostasis abantu abanayo yilokho okuholela ekugcinweni kokuqina okuhlobene ngokushisa. Ukushintshashintsha okungazelelwe kokushisa komzimba kungaholela ezinkingeni ezinkulu kakhulu, ngisho nasekufeni.
I- izinga lokushisa lomzimba elijwayelekile okwamukelwa ngokujwayelekile lokho kungu-37 ° C, kepha ngobubanzi obuthile obuphakathi kuka-36.1 ° C no-37.2 ° C. Ngaphezu kwalelo zinga lokushisa, kuzothiwa umuntu unemfiva noma umkhuhlane osezingeni eliphansi.
Bhekafuthi: Izibonelo ze-Thermal Equilibrium
Nazi izibonelo zokushisa nokushisa ezimweni ezihlukile:
- Ukushiswa kokushisa okukhiqizwa isibani.
- Inqubo yokushisa uketshezi, lapho ingxenye eshisayo inyukela phezulu nengxenye ebandayo iye phansi.
- Ukwehlukaniswa kwama-molecule aqukethe iyunithi yobukhulu, bese kuba ushintsho kusuka esigabeni samanzi kuya emswakeni lapho weqa ukushisa kwe-vaporization.
- Amanzi angaphezulu kolwandle, athola imisebe yelanga.
- Thinta isipuni ebesingilazini yobisi olushisayo kakhulu, futhi ngenxa yalokho sizoshisa.
- Ukushisa okutholwa ngumuntu ophekayo, yize engekho endaweni lapho kukhiqizwa khona ukushisa
- Udokotela, okuthi uma elawula isiguli athathe izinga lokushisa kwakhe.
- Ukuncibilika kobuningi beyunithi yento eqinile, lapho umzimba wedlula ekushiseni kwe-fusion.
- Ukuzivocavoca umzimba, okukuvumela ukuthi ushise ama-calories.
- Ukushisa kuxoshwa yinjini egijimayo.
- Amanzi lapho ebilisa, ngoba adlule u-100 ° C.
- Kuma-solid aqiniswe ngenduku, ukushisa kusakazekela endukwini.
- Isitofu.
- Indawo yokwelapha yezinto zokuphikisa, 500 ° C
- Inqubo yokushisa epanini, lapho ukugeleza kokushisa kusakazeka khona kwisibambo.
- Iphuzu lokuphela kwamanzi ezingxenyeni zensimbi, 250 ° C.
- Inqubo yokukhiqizwa kweqhwa, ebizwa ngokuthi ukuqina kwamanzi, lapho izinga lokushisa liba ngaphansi kuka-0 ° C
- Fudumeza amandla emgodini, osakazwa yimisebe.
- Into yesiqandisi esiqandisini.
- Ukukhanya okuza kithi kuvela elangeni, okuthwala amandla ngokusebenzisa imisebe.
