ʻO ka anakahi ana wela hōʻike i ka nui o ke kino o ka pae wela o ke kino, a i ʻole kahi kaiapuni. ʻO ka mahana kahi waiwai e pili ana i ka neʻe ʻana o nā hunaahi i loko o nā kino a i ka lewa, a ma muli o ia mea, hoʻoholo lākou nā waiwai ʻokoʻa o nā kino, ʻo ia paha ka mea kaulana loa o ka mokuʻāina: he mea maʻamau ka ʻike ʻana i kēia i ka wai, kahi e hoʻoholo ai ka mahana inā ke kino like (wai) i kūpale, wai a i ʻole kūlana kinoea.
Hana like ka mea like me nā mea āpau, hiki ke hoʻoholo i kēlā me kēia o lākou i ke kiko wela mai kahi e paʻa ai ma lalo a ma luna. wai (pae hoʻoheheʻe) a me ka lae o ka mahana o ka wai ma ka lalo a me ke kinoea i ka luna (puan mahu).
No laila, pono ka waiwai kino o ka mahana no ka mālama ʻana i nā kino a me nā mea, a me kēia mea nui e hiki ke helu. I loko o ka mōʻaukala e kū nei lākou nā ʻano ʻokoʻa o ke ana ʻana i ka mahana, hana no nā hihia like ʻole. ʻO nā mea nui ʻekolu e kikoʻī, i ke kaʻina manawa o ko lākou helehelena.
- ʻO ka kekelē Fahrenheit Ua hoʻolālā ʻia i ka makahiki 1724, a ua hoʻoholo ʻia ma lalo o ʻekolu mau helu i kahi ala e alualu ʻole ai kāna moʻokāki i kahi hōʻeuʻeu o ka pololei kaulike. Hoʻolahalaha kona hoʻohana ʻia ma ʻAmelika Hui Pū ʻIa, no ka hoʻohana ʻole ʻepekema.
- ʻO ka kekelē Celsius hoʻolauna ʻia i ka makahiki 1742, a ʻo ka hoʻoholo ʻana o kona nui i hana ʻia ma lalo o ka manaʻo o ka kekelē o ka hau a me ka paila o ka waiʻO 0 Celsius ke kiko e huli ai ka wai mai kahi paʻa (hau) i kahi wai (a i ʻole versa), a me 100 Celsius ka pae ma kahi, i ʻoi aku ka nui, hoʻolapalapa ka wai a lilo i mahu. Hoʻohana ʻia kēia pālākiō no ka nui o nā mahana i kēlā me kēia lā o ka honua, akā ʻike pinepine ʻia ia i nā ʻano ʻepekema like ʻole.
- ʻO ka hope loa, ʻo ka Kēkelē Kelvin i hāʻawi ʻia i ke kenekulia 19, a ʻike ʻia ma ke ʻano he pae mahana wela loa ʻoiai e kau ana i kona kiko 0 i ka pae ikehu haʻahaʻa loa, ʻo ia hoʻi, ke kiko e nele ai ka neʻe ʻana o nā hunaahi. I kēia ʻano, ʻaʻohe 0 Kelvin, a ma kahi kūpono o kēia ʻano e paʻa paʻa nā mea āpau. He mea maʻamau ia no ka hana ʻepekema a me ka hana ʻole no ka hana o kēlā me kēia lā, a ʻaʻole ia i hōʻailona ʻia me ka hōʻailona kekelē (°) no ka mea ʻaʻole ia he lohi akā he nui loa.
I kēia kaʻina o nā mea, pono i nā mahana ʻekolu he mau ʻano mōakāka e hoʻohuli ʻia. Eia nā mea hiki ke hoʻololi ʻeono i waena o nā anakuhi wela, a pehea e hana pono ai
