Ki te noho koe i runga i tētahi tūru rakau, ka mahana te mata o te tūru rakau. I tetahi atu taha, ki te noho koe i runga i tētahi tūru i hangaia ki te kirihou, ki te konganuku rānei, kāore te mata o te tūru whakarewa, kirihou rānei e mahana i muri i te noho ki runga. He aha te mata o te tūru rakau e mahana ai, engari kāore te mata o te tūru whakarewa? He aha te take e mamae ai te moe i runga i te papa makariri me te kore he moenga? Kua mau koe i tētahi koti makariri? He aha te nuinga o ngā koti makariri i hangaia ki te huruhuru hipi? He maha tonu ngā mea hei whakaaroaro me te pātai e pā ana ki te kaupapa o te whakawhiti wera mā te kawe hiko.
Whakaritea he rama me tētahi wahi waea angiangi. Puritia tētahi pito o te waea, ka pā atu tētahi pito o te waea ki te mura o te rama. Taria mō tētahi wā poto kia wera tō ringa. He aha i wera ai tō ringa? Ina pā tētahi pito o te waea ki te mura o te rama, ka neke te wera mai i te mura o te rama (te pāmahana teitei) ki tētahi pito o te waea (te pāmahana iti). Mā tēnei whakawhiti wera ka piki ake te pāmahana o te pito o te waea e pā ana ki te mura. Mā te rerekētanga pāmahana i waenga i te pito o te waea e pā ana ki te mura o te rama me te pito o te waea ka neke te wera mai i te pito o te waea e pā ana ki te mura ki te pito o te waea e pā ana ki tō ringa. Mā tēnei whakawhiti wera ka piki ake te pāmahana o te pito o te waea e pā ana. Kātahi ka neke te wera ki tō ringa matao. Nō reira, ka wera tō ringa.
Ina pā tetahi wāhanga o tētahi mea he pāmahana teitei ki tētahi mea he pāmahana iti, ka neke te wera mai i te mea he pāmahana teitei ki te mea he pāmahana iti. Nā te pūngao tāpiri ka tere ake te neke o ngā ngota me ngā ngota e hanga ana i te mea. I a rātou e neke ana, ka whai pūngao nekeneke ngā ngota (EK = ½ mv 2 ). Ka tukinga ngā ngota e tere ake ana te neke (me te pūngao nekeneke nui ake) ki ngā ngota i tō rātou taha. Kātahi ka tukinga ēnei ngota ki ētahi atu ngota i tō rātou taha. Ā, pērā tonu. Nō reira ka tukinga ngā ngota tetahi ki tetahi, ka whakawhiti pūngao. Ko te whakawhiti wera e puta ana mā te tukinga i waenga i ngā ngota e hanga ana i tētahi mea ka kiia ko te whakawhiti wera mā te ara iahiko.
Te tātai mō te whakawhiti wera mā te ara iahiko
He teitei ake te pāmahana o te mea kei te taha maui (T1) i te mea he iti ake te pāmahana o te mea kei te taha matau (T2Nā te rerekētanga o te pāmahana (T1 - T2), ka neke te wera mai i tētahi mea he teitei te pāmahana ki tētahi mea he iti te pāmahana (kei te taha matau te ahunga o te rere o te wera). He horahanga whakawhiti (A) me te roa (l) tō te mea e haere ana te wera.
I runga i ngā hua o te whakamātautau, ko te wera i whakawhitia i roto i tētahi wā motuhake (Q/t) he rite tonu ki te rerekētanga pāmahana (T1 – T2 ) , te horahanga whakawhiti-wāhanga (A), te āhua o tētahi mea (k = kawe wera) ā, he rite whakamuri ki te roa o te mea. Ko te tātai mō te tere o te whakawhiti wera mā te kawe:
Whakaahuatanga: Q/t = tere whakawhiti wera, k = kawe wera, A = horahanga whakawhiti-wāhanga, T1 = pāmahana teitei, T2 = pāmahana iti, l = roa o te mea.
Te whakamahinga o te whakawhiti wera mā te arataki
He aha te āhua o ngā taera he mātao ake i te whāriki? He nui ake te kawe wera o ngā taera i ngā whāriki. Nō reira, he pai ngā taera hei kawe wera, engari he ngoikore ngā whāriki hei kawe wera. Ina takahi tātou i te whāriki, ka rere te wera mai i ō tātou waewae ki te whāriki. Ka puta tēnei nā te mea he teitei ake te pāmahana o tō tātou tinana i te pāmahana o te whāriki. He ngoikore ngā whāriki hei kawe wera, nō reira ka kohia te wera e rere mai ana i ō tātou waewae ki runga i te mata o te whāriki, ka mahana ake te whāriki. Ina takahi tātou i ngā taera, i ngā uku rānei, ka rere te wera mai i ō tātou waewae ki ngā taera, ki ngā uku rānei. Nā te mea he pai ngā taera hei kawe wera, kāore te wera e puritia ki runga i te mata o ngā taera. Ka rere pai te wera, ka mātao ō tātou waewae. Mena kei roto tō whare i te wāhi makariri, me hipoki te papa o tō rūma moe ki te whāriki kia kore ai e ngaro te wera o tō tinana. I tetahi atu taha, ki te mea kei roto tō whare i te wāhi wera, kaua e hipoki te papa o tō rūma moe ki te whāriki nā te mea kāore koe e mātao engari e wera 😉
Ka pāngia pea koe e te mate mēnā ka moe koe i runga i te papa, kāore he moenga. He aha ai? Nā te mea he nui te wera e whakawhitia ana mai i tō tinana ki te papa. Ko te wera he pūngao e neke ana. Ina ngaro te nui o te wera i tō tinana, ka heke te nui o te pūngao. Ki te kore koe e kaha, ka pāngia koe e te mate!
He aha te mahi a ngā matapihi me ngā tatau? He aha me hanga ngā tatau me ngā matapihi ki te rakau? I te pō, he iti iho te pāmahana o te hau i waho o te whare i te pāmahana o te hau i roto i te whare. Nā tēnei rerekētanga o te pāmahana o te hau ka neke te wera mai i roto i te whare ki waho. Nō reira, i te pō ka kati tātou i ngā tatau, i ngā matapihi rānei. Haunga te whāinga ki te ārai i ngā kaihara, ko tētahi o ngā mahi a ngā matapihi, o ngā tatau rānei, ko te ārai i te wera kia puta mai i te whare. Ko ngā tatau, ko ngā matapihi rānei, he mea hanga ki te rakau. He iti te kawe wera o te rakau, ā, ka taea e ia te mahi hei ārai wera. Ko tētahi atu mahi a ngā matapihi, o ngā tatau rānei, ko te pupuri i te hau. Ko te hau e mau ana i roto i te matapihi, i te tatau rānei, he ārai pai (e ārai ana i te wera kia puta). He tino iti te kawe wera o te hau. Ko te iti o te kawe wera o tētahi mea, ko te uaua ake o te whakawhiti wera mā te kawe i roto i taua mea.
Haunga te pupuri i tō tātou tūnga hei tangata whai tikanga, hei tangata noa hoki 🙂, he mahi anō hoki ngā kākahu hei pupuri i te pāmahana tinana pumau. Ko ngā kākahu e mau ana tātou ka whakaritea kia rite ki te pāmahana o te hau. Ina tino iti te pāmahana o te hau, ka matotoru ake ngā kākahu e mau ana tātou. Mā ngā paraikete, ngā kākahu matotoru rānei (ngā koti, me ētahi atu) ka kore e neke pai te hau. Ka mau te hau i waenganui i te kiri me te koti, te paraikete rānei. Nā te mea he rerekētanga pāmahana i waenganui i tō tātou tinana me te hau kua mau, ka neke te wera mai i te tinana ki te hau. Mā te wera tāpiri mai i te tinana ka piki ake te pāmahana o te hau kua mau (ka mahana ake te hau). Tirohia te ripanga kawe wera i runga ake nei. He tino iti te uara kawe wera o te hau. Nō reira, kāore e taea e te wera te puta mai i te tinana. Ka mau tonu te pāmahana o tō tātou tinana. Ki te kore tātou e mau koti i te wā e tino makariri ana te hau, ka puta te wera mai i tō tātou tinana. Ko te nui ake o te wera e puta mai ana i te tinana, ko te nui ake o te pūngao e ngaro ana i te tinana.

Kōrero
I runga i te tātai mō te tere o te whakawhiti wera mā te kawe hiko, ko ngā āhuatanga e whakatau ana i te tere o te whakawhiti wera ko te kawe hiko o te konganuku (k), te rerekētanga pāmahana i waenga i ngā pito o te konganuku (T) me te roa o te konganuku (l). Kāore he pānga o te papatipu o te konganuku.
Ko te whakautu tika ko A.
