Roha waiariki o totoka me wai

Kei te mohiotia te reira e raro i te mahi o matūriki wera whakatere tona kaupapa tupurangi. Ki te wera koe i te hau, te rāpoi ngota e whakatu i te reira, noa rere atu i tetahi ki tetahi. Ko te wai wera he hua tuatahi i roto i te rōrahi, me ka timata ki te whakaeto. A he aha e tupu ki totoka? Ehara i nga tangata katoa o ratou e nehenehe e taui i to ratou ahua o te whakawhāititanga.

roha Thermal: Definition

roha Thermal - he huringa i roto i te rahi me te āhua o huringa pāmahana tinana. Pāngarau, ka taea e tetahi te tatau i te roha whakarea rōrahi, tuku ki matapae i te whanonga o ngā haurehu me wai i roto i te huri ngā āhuatanga o waho. Ki te tiki i te taua hua mo totoka, he mea e tika ana ki te tango i ki pūkete te tau whakarea o te roha rārangi. Kua tāutuhia Physicists he wāhanga katoa mo tenei ahua o te rangahau, a huaina ana e ia dilatometry.

Me Engineers me kaihoahoa mōhiotanga e pā ana ki te whanonga o ngā rauemi i raro i pāmahana tiketike, me te iti hoki te hoahoa o ngā whare, te faaineine rori me putorino.

roha o hau

tahi roha ngāwhā e roha o ngā haurehu i te rōrahi wāhi. tuhia te reira i Naturalists-philosopho i roto i nga wa onamata, engari ki te hanga tātai pāngarau tupu anake i roto i te ahupūngao hou.

Tuatahi o nga kaipūtaiao katoa paanga i roto i te roha o te rangi, i rite whakaaro reira ki a ratou i te mahi whaihua. E na te itoito rahi ka mau ratou ake te take, i riro hua rawa whakahē. Noatia, e kore e he putanga taua makona i te hapori pūtaiao. Tika o te inenga tei runga i ine te mea i whakamahia, te pēhanga, me te maha atu tikanga. Kua ara mai ētahi physicists ki te whakapono e kore e te roha o te haurehu whakawhirinaki i runga i huringa pāmahana. Ranei e kore he oti tenei fakafalala ...

Ko te mahi o Dalton me Gay-Lussac

Kua tonu Physicists ki tautohe ratou whango kua whakarerea te inenga, ki te kahore ranei Dzhon Dalton. Ia me tetahi atu ahupūngao Gay-Lussac, i te wa ano motuhake o ia atu i taea ki te tiki i nga hua ine taua.

I whai Lussac ki te kitea te take o te taua nui o hua rerekē, ka tuhia e te tahi mau mea i te wa o te wheako ko te wai. Noatia, kua puta i roto i whakawera ki te mamaoa me te nui, me te hanganga o te hau whakamātautau ke. Na reira, ko te mea tuatahi i hanga te kaipūtaiao - Kei te tino maroke katoa o nga taputapu, i whakamahia nei mo te whakamātautau, ka kingi i roto i ara te ōrau iti o te haumākū o te hau whakamātautau. ko nga wheako torutoru tuatahi atu nui i muri i enei whawhe katoa.

mahi Dalton ki tenei take roa atu i ona hoa, ka whakaputaina nga hua i roto i te timatanga rawa o te rau tau XIX. Te reira i te hau maroke kohu o te waikawa pungatara, me te ka te para i te reira. I muri i te raupapa o ngā, ka haere a Hoani ki te mutunga i whänui te haurehu katoa me te mamaoa e te take o 0,376. Lussac ka matou tau 0.375. ko te hua o te tūhuratanga mōhiohio tenei.

pēhanga Water kohu

roha waiariki o te haurehu, tei runga i to ratou elasticity, i.e. te kaha ki te hoki ki te rōrahi taketake. Ko te tuatahi ki te tūhura i te take ko Ziegler i te waenganui o te rau tau tekau ma waru. Ko e rerekē rawa nga hua o ana ngā. whika atu pono ko Dzheyms Uatt, e whakamahia nei mō te tiketike pāmahana kōhua papin, a mo te iti - inenga.

I te mutunga o te ahupūngao French XVIII rau whakamātau Prony ki ahu te tātai kotahi e e whakaahua te elasticity o hau, engari tahuri te reira i roto i cumbersome rerekē, me te uaua ki te whakamahi i. faaoti Dalton ki te manatoko empirically tātaitanga katoa, mā te whakamahi i te inenga siphon. Ahakoa te meka e ko te taua te pāmahana i roto i ngā katoa, tika rawa ko te hua. Na whakaputaina ana e ia a ratou i roto i te puka o te tepu i roto i te pukapuka ahupūngao.

Ko te ariā o te whakaetonga

Kua oti roha waiariki o hau (pēnei i ariā tinana) ngā huringa. Kua tamata Scientists ki te tiki ki te tukanga matua e hua mamaoa. Here ano, kua piro matou he ahupūngao rongonui Dalton. Kei te conjectured te reira e kukū tetahi wāhi haurehu e ki kohu ahakoa o ahakoa i konei e i roto i te awa ki (roto) tetahi atu hau kohu ranei. Na reira, e nehenehe tatou e faaoti e kore e te inu whakaeto mai tika ki whakapā ki rangi kōhauhau.

faarahi tīwae o te pēhanga hau i runga i te mata wai te wāhi i waenganui i te ngota, haehae motu ratou me te whakaeto, i.e. whakatairanga reira te hanganga o te korohū. Ko tonu te rua rāpoi ngota ki te whakahaere i te kaha o te mahara, na whakaaro pūtaiao e kore e te pēhanga kōhauhau pā te whakaetonga o wai.

roha o wai

wai roha Thermal uiui, i roto i te whakarara ki te roha o hau. rangahau Scientific mahi i roto i te taua pūtaiao. Ki te mahi i tenei, te whakamahi ratou he aerometry ine pāmahana, whakawhitiwhiti oko, me te tahi atu taputapu.

ngā katoa tahi me takitahi ta te ariā o Dalton e whakawhānui inu ōrite i roto i te rahi ki te tapawha o te pāmahana i ai e wera ratou. O te akoranga, kihai i te teitei te pāmahana, te nui te rōrahi o te wai, engari ko te tika hononga i waenganui ia ratou. Na ko rerekē te auau o te roha mō fluids katoa.

roha waiariki o te wai, mo te tauira, ka tīmata i te kore degrees me toro ki te heke te pāmahana. I mua, e hāngai ana ēnei hua whakamātautau ki te meka e kore e wai iho whakawhānui, me te maaro te ipu, i roto i nei kei reira. Ko etahi wa i muri mai, haere mai tonu ahupūngao Deluca ki te mutunga e kia kia rapua te take i roto i te wai. faaoti ia ki te kitea te pāmahana o tona kiato mōrahi. Heoi, i kore manuïa ia e tika ana ki te whakarerea e te tahi mau kōrero. kitea Rumfort, e kua ako tenei āhuatanga, e kitea te kiato mōrahi o te wai i roto i te whānuitanga o te 4 ki te 5 degrees.

roha Thermal o tinana

I roto i totoka, te huarahi matua, ko te ki te huri i te kaha tīwera o te roha o te wini whakakahokaho karaihe. I roto i te mau parau ohie, te ngota e hanga ake te rauemi, me e etaeta honoa i waenganui ratou, tīmata ki "ruru".

Ture o tinana roha waiariki whakatakoto e whai ake: i tetahi tinana ki te L rārangi taha i roto i te tukanga whakawera i runga i Dt (raorao T - te rerekētanga i waenganui i te pāmahana tuatahi, me te whakamutunga) whakawhānui e te nui dL (raorao L - ko te pärönaki o te tau whakarea o roha waiariki rārangi i roto i te roa o te ahanoa me te rerekētanga pāmahana). Ko te putanga māmā o te ture, i na roto i te taunoa e ki pūkete e whakawhānuitia te tinana i roto i ngā tohutohu katoa i kotahi tenei. Ko mo te mahi mahi mā te whakamahi i ngā tātaitanga nui atu cumbersome, mai i roto i te hono mo'oní, e kore e nga rauemi tikanga ahupūngao rite whakataruna me te pāngarau.

roha waiariki o te tereina

Hoki whakapanga te ara rerewhenua kua ngā tonu physicists Engineers, mai taea ratou tātai rite pehea kia kia nui tawhiti i waenganui i te hononga iho o te huapae ki te whakawera e kore e meangiti ara hauā ranei.

Ka rite ki kua whakahuatia i runga ake, te roha rārangi waiariki hāngai mō ngā totoka katoa. Na ko huapae kahore okotahi. Ko reira he kotahi taipitopito. noa puta papa rōnaki ki te kore e pāngia i te tinana i te kaha waku. Kua whakaritea nga huapae ki te takotoranga me te e paiherea huapae ki pātata, na te ture, e whakaahua ana i te huringa i roto i te roa, ka taea hoki ikuna'i e mau fifi i roto i te puka o te rere, me te reke resistance.

Ki te kore e taea e whakakorekore mo te huri tona roa, ki te huringa i roto i te pāmahana e faarahi te reira i te ahotea waiariki, e taea rānei te totoro kōpeke reira ranei. whakaahuatia ana tēnei āhuatanga e te ture o Hooke.
