Te Mārama ki ngā Tauhohenga Ā-Wāwera me te Ā-Wāwera
He āhuatanga nui ngā tauhohenga matū e tūtaki pinepine ana tātou i ia rā. Ehara i te mea ka puta noa i ngā taiwhanga engari i roto hoki i ngā tukanga maha e tū ana i tō tātou taha, pērā i te tunu kai, te whakamahana, te tahu wahie, tae noa ki roto i ō tātou tinana. Ka taea te whakarōpū i ngā tauhohenga matū ki ngā momo kāwai. Ko tētahi o ngā mea tino nui ko te mea ka tukuna, ka mimitia rānei te wera i te wā o te tauhohenga. I roto i tēnei horopaki, ka taea te whakarōpū i ngā tauhohenga matū ki ngā momo matua e rua: te exothermic me te endothermic.
Te Mārama ki ngā Tauhohenga Ā-waho
Ko ngā tauhohenga werawera he tauhohenga matū e tuku ana i te pūngao i roto i te āhua o te wera ki te taiao e karapoti ana. Ka puta pea tēnei pūngao i roto i te āhua o te mārama, te wera, ngā mea e rua rānei. Ka kitea tonutia tēnei tukanga mā te whakanui ake i te pāmahana huri noa i te taiao tauhohenga. Ko te tauira tino noa o te tauhohenga werawera ko te tahunga o te wahie, pērā i te rakau, te hau, te hinu rānei. Ina tahuna ēnei wahie, ka tukuna te pūngao i roto i te āhua o te wera ki te taiao.
Ko tētahi āhuatanga o tēnei tauhohenga ko te iti iho o te enthalpy o ngā hua i te enthalpy o ngā matū tauhohe. Ko te tikanga o tēnei ko te pūngao e tukuna ana i te wā e hangaia ai ngā hua he nui ake i te pūngao e hiahiatia ana hei wawahi i ngā hononga i roto i ngā matū tauhohe. Ko tētahi atu tauira ko te tukanga manawa i roto i ngā mea ora, ka pakaru te hukahuka mā te āwhina o te hāora hei whakaputa i te hauhā waro, te wai, me te pūngao.
Ngā Tauira o ngā Tauhohenga Ā-Wāwera:
1. Te tahunga o te Methane:
CH₄ + 2O₂ → CO₂ + 2H₂O + pūngao (wera)
2. Te tauhohenga i waenga i te waikawa me te kawakore:
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O + pūngao (wera)
I roto i te oranga o ia rā, ka tūtaki tātou ki ngā tauhohenga werawera i roto i te tukanga tahu wahie i roto i te ahi, i te oumu rānei, tae atu ki ngā momo tauhohenga e whakaputa ana i te wera, pērā i ngā ahi mura me ngā pahūtanga dynamos.
Te Mārama ki ngā Tauhohenga Endothermic
Ko te tauhohenga werawera te ritenga kē atu o te tauhohenga werawera. Ka mimitihia e tēnei tauhohenga te pūngao mai i ōna taiao i roto i te āhua o te wera. Nō reira, ka heke te pāmahana o te taiao e karapoti ana. Ka whakamahia te pūngao e mimitihia ana e ngā matū tauhohenga hei wawahi i ngā hononga matū tawhito, hei hanga i ngā mea hou. Ko ngā tauhohenga werawera e hiahiatia ana he pūngao tāpiri atu hei whakaoti i ngā tauhohenga werawera.
Ko tētahi āhuatanga o tēnei tauhohenga ko te nui ake o te enthalpy o ngā hua i te enthalpy o ngā matū tauhohenga. Ko te tikanga he nui ake te pūngao e hiahiatia ana hei wawahi i ngā hononga i roto i ngā matū tauhohenga i te mea e tukuna ana ina hangaia ngā hua. He maha ngā wā ka kitea ngā tauhohenga endothermic i roto i ngā tukanga taiao, pērā i te photosynthesis i roto i ngā tipu.
Ngā Tauira o ngā Tauhohenga Endothermic:
1. Te whakaahua-ā-tinana:
6CO₂ + 6H₂O + pūngao (mai i te rā) → C₆H₁₂O₆ + 6O₂
2. Te pirau o te konupūmā kāponāte:
CaCO₃(s) + pūngao (wera) → CaO(s) + CO₂(g)
I roto i te tukanga whakaahua, ka mimitihia e ngā tipu te pūngao mai i te rā hei huri i te hauhā waro me te wai hei kūhuka me te hāora. He mea nui tēnei tukanga ki te ora i runga i te Ao nā te mea koinei te pūtake o te mekameka kai.
Ngā Rerekētanga Matua i waenga i ngā Tauhohenga Exothermic me ngā Tauhohenga Endothermic
I muri i te mārama ki ngā whakamāramatanga me ngā tauira taketake o ēnei momo tauhohenga matū e rua, me tirotiro tātou i ngā rerekētanga matua i waenga i ngā tauhohenga exothermic me ngā tauhohenga endothermic:
1. Pūngao:
– Ka tukuna te pūngao e ngā tauhohenga waho-pāmahana ki te taiao, ko ngā tauhohenga mutunga-pāmahana ia ka mimiti i te pūngao mai i te taiao.
2. Ngā Huringa Pāmahana:
– Ko te tikanga ka piki ake te pāmahana o te taiao i ngā tauhohenga waho-pāmahana, ko te tikanga ka heke te pāmahana i ngā tauhohenga mutunga-pāmahana.
3. Enthalpy:
– I roto i te tauhohenga wera-ā-waho, he iti iho te enthalpy o ngā hua i te enthalpy o ngā matū tauhohe. I tētahi atu taha, i roto i te tauhohenga wera-ā-roto, he nui ake te enthalpy o ngā hua i te enthalpy o ngā matū tauhohe.
4. Te ahunga o te Pere Pūngao i runga i te Kauwhata Enthalpy:
– I roto i tētahi tūtohi enthalpy mō tētahi tauhohenga exothermic, ka anga te pere pūngao ki raro (e tohu ana i te tukunga pūngao), i roto ia i tētahi tauhohenga endothermic, ka anga te pere pūngao ki runga (e tohu ana i te mimiti pūngao).
Te Whakamahinga i roto i te Oranga o Ia Rā
He mea nui te mahi a ngā tauhohenga exothermic me ngā tauhohenga endothermic i roto i ngā āhuatanga maha o te ao me te ahumahi. Anei ētahi tauira:
Tauhohenga Ā-waho:
1. Te Mahanatanga o te Ao:
– Mā te tahunga o ngā wahie pūngoi hei whakaputa pūngao ka tukuna he nui te pūngao wera ki te āhuarangi, ka whai wāhi atu tēnei ki te mahana o te ao.
2. Te Ahumahi me te Whakaputa Hiko:
– Ka whakamahia ngā tauhohenga werawera pērā i te tahunga o te waro me te hau māori i roto i ngā tipu hiko hei whakaputa pūngao.
3. Haumarutanga:
– He maha ngā taputapu haumaru pērā i te ahi puni, i ngā mea pahū rānei, e mahi ana i runga i te mātāpono o ngā tauhohenga werawera.
Tauhohenga Endothermic:
1. Ngā Taputapu Whakamatao:
– He maha ngā taputapu whakamatao pērā i te huka maroke me ngā putea whakamatao e mahi ana i runga i ngā tauhohenga endothermic e mimiti ana i te wera mai i te taiao, ā, ka puta te whakamatao.
2. Te Hanganga o te Ozone:
– Ngā tauhohenga wera nui i roto i te āhuarangi, pērā i te hanganga o te ozone, e mimiti ana i te hihi UV mai i te rā, e tiaki ana hoki i te whenua.
3. Tukanga Ahumahi:
– Ko ētahi tukanga ahumahi, pērā i te tukatuka rino me te maitai, te hanga rānei i ētahi matū, he tauhohenga werawera e hiahia ana ki te whakauru i te nui o te pūngao.
Whakamutunga
Ko ngā tauhohenga exothermic me ngā tauhohenga endothermic he momo matua e rua o ngā tauhohenga matū e whai wāhi nui ana ki ngā tukanga taiao me ngā tukanga ahumahi. Ka tukuna te pūngao e ngā tauhohenga exothermic, ka mimiti te pūngao e ngā tauhohenga endothermic. Ko te rerekētanga matua i waenga i ngā mea e rua kei roto i te whakahaeretanga o te pūngao i te wā o te tauhohenga.
Ehara i te mea he mea nui anake te mārama ki ngā tauhohenga exothermic me te endothermic mō ngā kaipūtaiao me ngā miihini, engari he mea whai hua anō hoki i roto i ō tātou oranga o ia rā. Mai i te pūngao e whakamahia ana e tātou i ia rā ki ngā tukanga koiora e puta ana i roto i ō tātou tinana, kei ngā wāhi katoa ēnei momo tauhohenga e rua. Nō reira, mā te ako mō ngā tauhohenga exothermic me te endothermic ka kitea he māramatanga hohonu ake ki te ao matū me ngā tukanga e whakahaere ana i te ora i runga i te whenua.
